FlexTruder

FlexTruder Universal printed bowden extruder that can print any flexible material
Please note: The FlexTruder is suitable for any PTFE Tube Push Fit Connector causing it to get stuck.
The default extruder was hard to modify so I needed a quick solution to print my flexible parts and ordering a new extruder were not an option since I hate to wait for the slow boat from China or any other place.
I thought what are the parts I have in handy, I have the Tevo default extruder and its parts and I have M3 I recommend this mix with various M3 sizes.
PTFE tube pneumatic adaptor M5 1 pcs
MK8 extruder drive gear 1 pcs

V623ZZ V groove roller wheel ball bearing 1 pcs
7.5*5*20mm Steel Feeder Spring 1 pcs
