Summary

This ink pen works with "Stabilo EASY original" ink cartridges.

Suitable for right- and left-handed use.

The top section has a 3mm hole to where you can attach your own, fancy creations.

Instructions

Print these three parts:
- InkPen_bot.stl
- InkPen_top.stl
- InkPen_cap.stl
  I recommend an infill >=80%.
Stick an ink cartridge into the bottom part.
Check if the tip looks like on the image ("IngPen_tip.jpg").
If not, carefully(!) grind or drill the inner of the tip.
Screw on the top part.
If there is a gap, use an 8mm drill and manually drill
into the top part until it fits.
Design your own PlugOn part with a 3mm hole at the bottom.
Attach it with a bit of 3mm filament and glue or use a threaded rod.
Go out and brag about it...
