4xidraw Drawing Machine (modified/combined/improved)

Print every part once, except for `end_X.stl` and `carbon_rod_cap.stl`, which you both need twice. I used 40% infill for all parts.

Follow the original assembly instructions from [instructables.com/4xiDraw](https://www.instructables.com/4xiDraw/). I added aluminium tubes around the M10 threaded rods.

For a robot that can draw on A4, I used the following dimensions:

* 8 mm rods X axis: 430 mm
* 8 mm rods Y axis: 320 mm
* M10 threaded rods: 440 mm
* aluminium tubes: 382 mm
* GT2 belt: approx. 1600 mm

Note that I'm currently working on an improved pen carriage using a linear guide rail. I will update this page when it's ready.

See below regarding software options that still work as of December 2024.
