Swiss Tech Mini Multi-Tool Case Design

I realized I over-engineered this one…the multi-tool itself doesn’t need a case or holder to add it to a key-chain. BUT, I enjoyed the creativity nevertheless.

My Insulated Water Bottle (Filter Cap?) Easy Twist Redesign

Here is my redesign of this second cap – a simple finger gripping nub to provide leverage to screw and unscrew it for fill-ups or to add ice. I don’t understand why they wouldn’t include some physical aid given how difficult it is to open…

Engagement Ring Notched Wedding Band Test Fit

My fiancé wants a wedding band that is flush with her engagement ring. To do that, it would require cutting a notch from a flat wedding band. So I created this and another size to have something to bring to a jeweler as we explain what we want (before we buy and they cut).

Door Deadbolt Lock/Unlock Guard (from my dog)

I created a guard for my door’s lock which has a lock/unlock feature preventing the deadbolt and key from turning. Sometimes when my dog gets excited, she jumps on the door and she has locked my out one too many times resulting in crawling through the window…No more!

Espresso Portafilter Tamper with Embedded Weight

The tamper that came with my espresso machine probably costed the company $0.05 at scale to include in the kit. I knew I could spend $0.05 and a 1 inch stainless steel ball bearing to create something that actually works. Designed the tamper to have a cavity to allow me to pause the print and drop in the weight.

Arduino Garmin LiDAR Prototyping Base

I designed and built a sturdy, functional base to securely hold the Arduino, Garmin LiDAR sensor, LCD display, and all necessary wiring. This robust foundation enables me to prototype a device that measures the distance to the car ahead and detects changes in its speed, providing critical alerts when the vehicle slows down. The base is specifically engineered to support the components during testing, ensuring stability and ease of use throughout the development process.

Toilet Flush Handle Adapter Washer

Our toilet flush handle was sticking and wouldn’t return to the top position. This caused the water to continue filling the bowl. The handle “arm” was dragging and grabbing onto the side of the toilet bowl. I created multiple versions to solve the problem and accommodate the installation process. Version 2.0 also had a slot so one wouldn’t need to take the nut or the chain off and I included a tab to help grip the piece while tightening the nut. Get STL.

Toilet Flush Handle Adapter. Our toilet flush handle was sticking and wouldn’t return to the top position. In doing so, the water would not stop filling the bowl. The handle “arm” was dragging and grabbing onto the side of the toilet bowl. When I took the nut off and held the handle assembly at an angle so the arm is parallel to the bowl’s side, it stopped dragging and worked fine. Created an updated version once I realized that to install, you had to remove the nut and the chain in order to loop the part through (like a washer). Version 2.0 also had a slot so one wouldn’t need to take the nut or the chain off and I included a tab to help grip the piece while tightening the nut. A "T" label affordance was added to the top to distinguish the top from the bottom.

Book Pen Holder

You’re probably wondering…why not simply clip your pen or highlighter to your book? If you’re anyone like me, you write a lot in a book and you prefer to read, when standing or sitting on the couch, or even on the toilet. So instead of setting my pen down on my chest or my ear, I designed an printed a holder that clips into any book and hold a pen and highlighter.

Window Blinds Fix

Simple, but thoughtful. The nubs are experiencing a shear force when installed and so I printed one of them horizontally to maximize strength, and the other vertically. Many of you might know this already, but the one printed horizontally has a larger surface layer contact which makes separating the layers much harder, aka can withstand some force. On the other hand, the one printed vertically has circular surface layers the size of the diameter and when a force is applied, could separate aka break. #MechanicalEngineering

Anti-Escape Cord Holder

This was a simple solution to a rather large inconvenience of mine. Of course, it’s very specific to my laptop cord; however I am working on a more generalized solution for any cord (even USBs) and for multiple desks. I like to add personal flares to my designs that either stimulate other ideas, inspire me, or simply make me smile. Always Create! Cheers.

Mug Cupholder Adapter

This was one project I have been putting off for a long time. I love my mug too much to part ways with it.

This was one project I have been putting off for a long time. You would think that I would have chosen a different coffee cup or designed something by the third time my coffee spilled all over the car console. But no, I have been dealing with spilt coffee or a precarious grip on my mug while driving for over a year now. It wasn’t until my design-something-new-everyday exercise that I decided to finally design something for this huge inconvenience of mine.

3D Filament Spool Holder Adapter

To reduce the rolling resistance of a full spool with the small axel, I created a universal fit adapter to fit every filament spool on this base’s axel. Now it rolls easily. One thing to note: it was designed for manufacture, meaning I printed it in two parts the way I did to avoid supports and make it easy to use.

Swiveling Bike Mirror Handlebar Bracket

The bracket that came with the mirror which fits in the end of the handlebar would slip out as I’m riding and the bar is vibrating. So I 3D Printed a more permanent solution which I’ve been using for 2.5 years so far. I had to print it in PETG because it kept loosening when I made it in PLA and stored in my shed. Also made an end cap on the other side because those pesky things keep falling out.

3D Printer Camera Mount

I had a network camera and wanted to mount it to my Ender 3, 3D printer so I didn’t have to keep checking if my print was done. I created the bracket that mated with the camera I had and another bracket that kept the wire out of the way of the print bed and other moving components.

Folding 3D Printer Brackets and Linkages

See this project page for more details. Sadly, it’s not complete…yet

For my design, I opted for a toggle clamp to connect the top and bottom sections of the printer. Two side brackets were made to attach the sections together. This solution offers a fast and highly secure method for aligning the two portions effectively. My approach aims to reduce reliance on off-the-shelf components by incorporating more 3D-printed parts.
Inspired by Proper Printing's Folding Printer Project, I was impressed by their innovative folding mechanism. However, I envision a different design that offers greater security, ensuring better accuracy after folding and unfolding. My approach aims to reduce reliance on off-the-shelf components by incorporating more 3D-printed parts. MotionGen.io prototyping the foldable 3d printer.

Minion Rubber-Ducky Fusion

To be clear – I DID NOT design this. The minion with the wild hair and the rubber duck were both .stl files that a dad sent me, asking if I could combine the two together for his son. His son was obsessed with purple, minions and rubber duckies so he wanted to earn Dad of the Year by getting this made for his son. I was lucky to be a part of it!

3D Printed Bowties

I’m obsessed with bowties, what can I say…I made 5 or so other designs that I’ve since given away or need to take pictures of.

Screen Door Holder

My front door is quite annoying in that it closes so fast behind you. You almost need to jump in sort of like Indiana Jones just to avoid the door hitting your heel. But the real reason for wanting to create something comes from bringing my bike in and out of the house. Not only is this door holder cute, it also slides forwards and backwards, remaining on the railing to be used whenever we need. The hook-like features on the ends keep it from sliding off the square tubing which gives it a hard stop.

Broken Car-Key ‘FixIt’ Case

A student in my class came to me complaining that he keeps losing his car keys. After asking him why, he proceeds to pull out one loose key. A few hours of measuring, modeling, printing and prototyping, we have a solution.

Mystery Boxes

I was introducing observational experimentation in my physics and engineering classes as an activity. These “Mystery Boxes” were designed and 3D printed and a marble was placed inside. The boxes were then given to students and told to play around with it, experiment different “moves” to figure out the inside cavity shape. They wrote down their observations and told to test them.

Physics Demonstration – Simultaneous Ball Launcher & Dropper

Designed and built for my physics classroom. In 2D Kinematics, we learn about the independence of horizontal and vertical motion. Both balls hit the ground at the same time because they accelerate downwards at the same time, regardless of launch speed. This teaching device I modeled helps demonstrate this.

DIY Physics demo tool. A 3D printed golf ball launcher and dropper. I built it using a gate latch which is zip tied to the custom base I designed. one golf ball lays on a platform and gets launched while the other has the gate latch rod inside of it and gets dropped (golf ball with a hole). The whole platform attaches to a chemistry clamp stand.

Attachable Kayak Fin (for prototyping)

A Kayak fin attachment that allows a strap to pass through it and attach to most boats. I made this for a kayak I had that couldn’t track straight at all. This was a prototype model before it would’ve been permanently mounted. (Sold it before I got to do that)

Trig Tool for Students

A tool I created which helps students determine which component vector is which side and therefore help with determining which trig function to use. Some students really need that extra support, so why not create things for that?

Schwinn Tandem Bike Tensioner Pulley Fix

The tandem bike I purchased for my proposal had a broken chain idler/tensioner pulley. A few measurements later, printed a solution for that fix. Printed in PETG for its weather resistance and durability.
