This a yet another Wanhao Duplicator i3 pen holder.
It's designed to mount to the extruder fan port, and needs very little to get you going!
Things you'll need:
- 3x 3mm bolts/screws
- 3x 3mm nuts
The drawing part is a little tricky the first time through, but makes more sense as you use it more.
The basic slicer settings are:
- Extruder temp: 0
- Hotbed temp: 0
- Z lift on retract: 5mm (3mm and up is good)
- Retract distance = 0.01mm
- Minimum distance to retract: 0.1mm
You then set the model to the Z offset of your paper/pcb/card/etc. and print it, watch it carefully as it makes the first line (if your zdepth is off, you pen will be mushed into the surface; I'm adding a springed design soon that will sort this issue out)
any (I used 0.1mm layers)
