Update original design to fit Ordbot on seringe side.

Use 4mm rod

make a cone to lock the 1,75 to 3mm filament and adapt the plastic cross to fit european seringe

You need to print 2 files and get a 20ml seringe

Update 1:
-Add a cone for a easier filament insertion
-translatiton for the cylinder to be in front of the filament hole.
- 4mm hole ( instead of 3 ) to use the original nuts and bolt.
