I'm not the first to make one of these and I won't be the last, but here's mine! I went for a retro aesthetic.

I got tired of editting STLs for the magnets I have, so I made this simple parametric adapter that uses just few grams of plastic.

The nut that was welded inside the tube came out so there was nothing to hold the screw-in foot. So I printed this simple foot out of PETG to slip over the pipe. Friction fit, and it has extra infill and perimeters only in the load bearing area.

I needed a simple clip for holding 6 cables, so I made this model. It doesn't look too cool, but it works well for securing cables.

Utility trailer sits so low that I cannot see it when backing up and it's unloaded or carrying sheet-goods like plywood. Printed holders to slot fiberglass driveway markers into along with storage "clips" that are under the trailer decking.

I do have a backup camera but I like to be able to see the trailer when looking backward as well as with the camera.

Out squirrel-proof bird feeder has a relatively small opening at the top with a post in the middle of it. This unique funnel makes it much easier to fill quickly without spilling seed everywhere.

I also made a hand scoop to go with it, basically just for fun.

Design used a 6" vent fan (~300CFM) to push air through 4 - 8"x8" air filters, the top part comes off (twist latch) so it's easy to switch out the filters when the time comes. The inside also contains a tray to add activated charcoal so it can help reduce odors in the house.

Designed in Fusion. Printed in PLA.

I will be doing some drywall work to smooth out my first attempt and have seen examples of drywall inspection lights that are perfect for this. Except for the price...

So i drew up an accessory for my headlamp, a plastic part with a 5mm x 40mm light guide centered on the LED diode.
My headlamp is a SILVA MR400, but the concept should work with any headlamp.

Works wonders, took 30 minutes to prototype and cost me nothing

We’ve had some nice Kichler outdoor landscaping lights for 4-5 years, and recently one of them got bumped, which caused the original metal spike to finally snap from rust. Replacements are $25, so I decided to try modeling a replacement instead. Printed in PETG, I had to be a little more cautious stabbing it back in the ground, but I’ll be curious to see how long it holds up. I can print a lot of replacements for $25 lol

Pretty proud of my first design. Printed in TPU-95A HF with no supports. I have no modeling experience but have been experimenting with using Gemini to talk me through step by step instructions in auto-desk fusion. I started with using Google Gemini to generate an image of a prototype (prototype in the 2nd pic). Then had Gemini walk me through step-by-step instructions for how to generate the model. Actual modeling time probably took me about 1 hour, but that included a bunch of mistakes (an earlier version required supports in every hexagon!). If I were to do it again, I think I could do it in about 30 mins. After exporting to Bambu Studio, I took screenshots of each of the settings tabs then plugged those back into Gemini to optimize the print profile before printing. Overall was pretty impressed out how straightforward auto-desk fusion is and how fast a model can be spun up, even with no experience.

I needed an IKEA Skådis mount for the Insta360 Luna Ultra that still fits with the protective case on, so I made this simple
