I saw someone attach a PET bottle to an extension pole and use it to scrape moss off their roof.

So I made an adapter with threads to screw on a PET bottle and tried it myself

Most of the gearbox designs I saw online are .step or even .stl files that are hard to modify and with no real "design" aforethought, working mostly by accident...

So I made this fully parametric design where you can change gear ratio, module etc...but most importantly, I wanted to follow some kind of a systematic approach.

Truly open source, copy it, modify it, sell it..go wild...

​I was tired of the shitty plastic cases these blades come in — they’re a pain to open and the blades always get stuck. Since I’ve been on a utility knife design spree, I figured it was time for a decent storage solution.

​Designed this with a rotating tray so you can actually grab a blade without fighting the box. I made a desktop base and a wall-mount version since my workbench is always a mess anyway.

Printed on the P1S with Bambu white PLA. No supports on the main body, designed for easy printability.

The stand holds the MagSafe puck via a snap fit, and the cable routes through the base so nothing hangs loose on your desk. Took a few iterations to get the snap tight enough to feel solid but easy enough to assemble without tools.

Part of a larger modular Apple desk system im working on.

The story.

I made this to solve a problem: my stuff is always sitting in different places, which does two things. It means that it takes me longer to find, and it doesn't get shown off; it's just there. So I decided to design a wall organizer. When I started designing this, I had a few rules for myself: firstly, that it had to be modular. Then it also had to be something that I would actually put on my wall and use every day. I also designed the main pen bin with a rounded shape because it has a very welcoming feel and would add visual appeal.

This knife has a special locking mechanism to fix the blade with zero wobble.
Its a little tricky to lock and unlock one handed and this lever fixes it.

​I wanted a knife where you don't have to hunt for specific metal screws or parts. Everything here is printed—including the screws holding the grips.

​Features a quick-release mechanism to swap standard trapezoid blades in seconds without tools, plus a wire stripper notch.

Just uploaded this door strike plate / deadbolt plate model to MakerWorld.

Simple print, but maybe useful as a replacement or quick fix.

My collection is growing.
My kids absolutely love them

What animal should I add ?

I got tired of the constant gap and my monitors never staying flush. Designed this adjustable clip to lock them together once and for all. Just 3D printed parts and some double-sided tape—finally, a seamless setup!

Hi guys! I wanted to share with you some angle brackets that I made!

What do you think about it?

I have 3 different version, If you want to check and tell me how to improve them would be so nice!

(I posted this a couple days ago but found an issue at the last minute I wanted to fix and took it down so here's take 2.)

A print-in-place gyroscopic ring spinner shaped like a shuriken. No assembly, no supports, no hardware,  just flex the rings loose straight off the bed and spin.

I’ve been working on a new sculptural piece that serves absolutely no practical purpose! It’s made of 25 individually printed pieces in petghf that are glued together and adhered to a plywood backer.
