Required parts to quickly build the simple plotter featured in "Make:" magazine 01/2020 (https://www.heise.de/make/artikel/Der-einfachste-Plotter-der-Welt-4653323.html?hg=1&hgi=3&hgf=false). More info to be found here: https://brachiograph.readthedocs.io/en/latest/ base.stl upper_arm.stl forearm.stl (a bit tricky to print as it needs some support) Servo motors are "Tower Pro Micro Servo 9g SG90". Screws I used to attach the Raspberry and the servo motors:SPAX 2,5x10. Use some force (tongs?) to push the servo arms into the openings in the "upper_arm", they are made to fit tightly. I additionally added some glue. Then screw into the servo head with one of the two bigger screws that came with the servos. Improved in the latest version (thanks for your comments, ObiMuli!): - stripped the base for less material use and faster printing - two mounting points are enough to fix the raspberry. I added a third one to allow easy fixing of pi zeros (in "landscape" orientation) - a new area on the left hand side to better fix the base to a table - a tunnel in one of the base servo fixing towers helps to route the cable - the forearm is reinforced with an additional edge The onshape sources if you are interested: https://cad.onshape.com/documents/34086f2e6c7544a98548dc48/w/2419dd3189189a2b673bac4b/e/bea7f526d553e0ff6c659f11
