My modifications on the original Printrbot Plus.
- Quick-Fit X-Carriage with larger space for the extruder (especially for my Budaschnozzle hotend but can hold 4 hotends) derived from thingiverse. Special thanks to RichRap for the original idea,
- Quick-Fit Extruder derived from Greg's Hinged Accessible Extruder with New Motor Mount that fits the printrbot original ubis hotend,
- Fanduct adapter for this one on thingiverse,
- Push-Fit (M6 thread enabled) compatible extruder idler,
- 20cm x 21cm borosicate glass (from lulzbot.com) holder,
- Printrbot Plus nut keeper, derived from this and available on thingiverse too,
- Z-stop dial with knurled top,
- Y-Axis bearing guide compatible with original Printrbot Y-Axis stabilizer derived from thingiverse,
- Push-fit filament guide for Printrbot Super-Z,
- Wades extruder bowden setup adaptor for Printrbot Super-Z,
- Quick-Fit Ubis Hotend Push-fit bowden adaptor,
- Polakium Engineering X-Axis for Printrbot LC and Plus support for the part #10.
All the Push-fit fits 6mm OD tubing (PTFE is better) and has a M6 thread at one side. I usually drill them with 3.5mm bit. I also drill a chamfer using a 4mm bit and a 5mm bit.
