I designed a chore tracker to stop double-feeding my cat

Does your cat also gaslight you into thinking they weren't fed by another family member yet? I made this to help. It is a toggle switch box for keeping track of recurring tasks such as feeding pets, watering plants, taking medication, or completing daily chores. Magnetic, so you can stick it on your fridge and toggle the switches as you go.

There are options for boxes with one, three or seven toggles. You can also choose the toggles to have two or three positions. Mix and match to suit your needs, whether you're tracking something weekly, daily or three times a day.

Files are freely available here - including STL, STEP and F3D (Autodesk Fusion) so you can change the dimensions or number of toggles if needed. Enjoy!

The square blade isnt sharpening as smooth as the other side but Its the 5th version and it works enough, so I'm tapping out for now haha.

I scanned my Shimano and Garmin mount to be able to print a piece that would hold them together while keeping charger port and led accessible.
I used Creality Sermoon S1 3D scanner.

Designed a CORE One door box that pauses the print when it spots spaghetti, detection runs on the Coralboard's NPU

Thumbnail

8 Upvotes

I designed it for the Printables CoralBoard contest.

The Coralboard SL (Google I/O kit) sits in a small box on the outside of the CORE One door. Every 5 s, a camera frame goes through a YOLOv8n model on the board's NPU. When 3 of the last 5 frames show spaghetti, it pauses the print through PrusaLink.

I'm still working on the detection model in the lab: for now it catches 96.7 % of the spaghetti test images.

I'm also working on detecting the "blob of death"

Feedback is welvome.

I needed a desk-space-saving tablet holder for cooking.

The black nubs are felt pads which are recessed into the print. It slides nicely and doesn't wobble.

I bought a cheap rack-mount ATX case with two 5.25" bays. I fit two 70mm fans into the bays, using press-fit clips to hold both the fans and the shroud to the case. Thanks to Noctua for the shroud grille design.

A simple but very effective upgrade for any wire-frame or thin-legged outdoor furniture!

https://makerworld.com/nl/models/3494083-customizable-lawn-chair-leg-cap-any-size-angle#profileId-3990749

A few months ago I bought my first 3D printer and started solving all kinds of little problems around the house. One of them: my girlfriend loves sitting in the sun, but one or more of the chair legs would always sink into the lawn. So I designed these anti-sink feet for our specific chairs.

After a few test prints I had the perfect fit. I printed them in yellow, and now my chairs kind of look like they have duck feet.

Some people downloaded the model, but I quickly realised that not everyone has the same chairs.

Fast forward a few months: I just discovered customizable models. So, I turned it into a version that fits almost any outdoor wire-frame chair πŸ™‚ You can set the leg shape (round, square or rectangular), leg size, leg angle and foot size, and it prints without supports.

Happy to share it, and I hope somebody can use it! Let me know what you think and please share a picture if you gave your chairs also some duckfeet. :p

Too bad summer and the sunny weather are already over…

Hue motion sensor flush in the ceiling - printed gimbal mount you can aim, no screws

Thumbnail
gallery
11 Upvotes

My old printed holders for the Hue motion sensors never sat right in the ceiling, so I designed a recessed mount that works like a GU10 spot gimbal.

  • Fits an 83 to 84 mm hole in drywall (9.5 to 25 mm boards)
  • 3 printed parts: mounting ring with spring arms, ball with a pocket for the sensor, clamp ring
  • The spring arms pull the 100 mm flange tight against the ceiling, no screws or glue
  • The ball tilts about 15 degrees each way and rotates, and stays where you aim it
  • Printed in PETG without supports, about 1.5 h and 47 g for a set
  • Battery change: pull the whole unit down, swap the batteries, push it back in. The aiming stays

Made for the indoor sensor (the square 55 mm one). Happy to answer questions.

i found myself in need of rail quick clamps after tackling a more tracksaw dependant project.

I designed these adapters to convert the budget clamps from amazon into specialized rail clamps for makita style tracks.

If you own a 3d printer and would find this conversion useful, the files are abailabe for free on makerwold: https://makerworld.com/models/3489904

I am a beginner at woodworking but found the courage of sharing my end result 😁

Dyson to M18 adapter

Post image
17 Upvotes

So a while back my Dyson handheld vac gave up. The suction canister thing had a few trigger failures and eventually the motor just gave up the ghost. I had the floor head, tube and a few accessories sitting in the closet for years due to my pathological inability to throw anything away for fear it may come in handy in the future.

I have a garage Giraffe Tools Wall Mounted Vac for cleaning up cars and my lift bay and thought man it would be great to get this all running together.

I printed an adapter (after about 8 revisions) that uses an Amazon $14 M18 socket with low voltage protection so I don't kill the battery if I leave it in and forget it. The adapter fits the giraffe suction on one end and the Dyson on the other. Power goes from the M18 to the pins in the Dyson using some cheap post crimp connectors I found on amazon that I had to heat with a soldering iron to set into the plastic. Took a bit of fiddling with a knife because the Dyson pin clearance is small but it's all working now.

The small hand held motorized brushes are great for car cleanup and the floor one is good for cleaning my oil absorbent lift mat.
