How I 3D print gears using POM (Delrin)
POM (Delrin) is the gear plastic in consumer robot vacuums, and notoriously hard to 3D print. Here is how I print it reliably: two sacrificial PETG layers first, then POM.

How OOMWOO’s 3D design gets made
OOMWOO’s mechanical design is not drawn from a blank sheet. It starts by researching ready-made parts that can’t be 3D printed (motors/sensors), capturing their dimensions, tearing down and reverse-engineering consumer vacuums to learn the state-of-the-art – and remaking that into…
OOMWOO Vacuum – Build Instructions
Future home for OOMWOO open-source vacuum cleaner robot build instructions. Bring-up notes for the sourced motors, fans and sensors – connectors, pinouts and measured currents – are in hardware bring-up, and the CAD pipeline behind these parts is in how…
Building an Open-Source Robot Vacuum — Meet OOMWOO
I’m starting a new build-in-public project: oomwoo, an open-source robot vacuum you build yourself. Raspberry Pi, ROS 2, 2D LiDAR, Home Assistant, 3D printed, local-first — and open from the first commit.
How to scrape 3D-printed plastic off the build surface properly
If you are reading this post, chances are you have some trouble scraping plastic – of even removing entire 3D-printed parts – off the build surface. There is a bit of a know-how to this chore – here is how…
