Including updated build instructions, with many pictures: https://github.com/paenian/i3_parts/wiki
The instructions are a work-in-progress, and take you from parts to working printer. You'll need to source and cut the files yourself.
Notable improvements:
- Fully braced top frame
- Y endstop now lives inside the printer
- LCD is up top - shortens the cables required, should let you use the factory supplied cables
- electronics and power supply mounting holes are in there
- More zip tie slots for wire routing
- Half-decent instructions in a wiki!
- Feel free to update and improve the wiki.
- Unfortunately, the wiki doesn't easily let you upload pictures - I'd like to have them all internal, not linked to other sites - so please let me know if you add pictures, I'll copy them and host 'em on github.
