Yet another Wanhao Duplicator i3 - Pen Holder

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.
