Product Description

A guide pin is designed in to show pivoting point but should be broken out prior to fitting the pivot screw.


The tolerances are nice and close around the bearing and knurled drive so that it can be used to feed ninjaflex. If you have to drill any material out of the filament holes, don't enlarge past 2mm. There is a mini funnel on the output stage coming off the rotating surfaces and this has been easier for me to feed filament through than any past bowden feeder I've used!


Extra parts required:

Stiff spring. Should be hard for you to compress the arm against the spring.

3 x M3 x 8mm machine screws.

1x M3 x 16mm machine screw and a few M3 washers.(for the arm)

1 x M4 x 10mm machine screw.(for the bearing) )

10mm fine pitch bowden clamp for tube for 4mm OD tube. ( )

9mm diameter drive gear:



Long direct drive 400 step per rev low voltage Nema 17. ( ) side mounted.
