A print head top for 1.75mm filament and 4mm bowden tubing.

It is a pretty straight forward replacement of the top part of the print head even if it requires you to disassemble the whole printhead :-)
I use the 1.75mm filament with a modified version of IRobertI's feeder.

Materials and methods

- 3DSolex 1.75mm Olsson Block
- 4mm bowden coupling (search for "Bowden Coupling 4mm" on Aliexpress and you will find)
- Printed 4mm bowden clip (you can find it amongst my other designs)
- 4mm OD/2mm ID bowden tube

Nice design - printed it real quick and works - but - can you build a dual one?
