Description
Modified version of Takei Naodar's feeder, which was a modified version of iRoberti"s feeder.
-adjusted tension settings, zero tension is now possible up to full spring max tension.
-revised outer casing at rear for 2 screws instead of 3, as well as made it symmetrical.
-adjusted some tolerances
-2 designs, one with stock tension screw and nut, another with socket cap screw and square nut.
Step-by-step instructions included
While not a quick change feeder, this is a workhorse feeder. It is simple and just keeps working, period. It will feed flexible filaments, no problem. It has a huge range of tension adjustments for a wide range of filament diameters and types.
Lots of credit to those guys for a great starting point in a reliable feeder design.

Comments
How do you actually change the filament? Do you just push in a new one and it starts rolling in? There is no open-close mechanism like on iRoberts V2 feeder.
I made some modifications to this design to get it working on my Frankenstein UM Original (https://www.youmagine.com/designs/modified-sp3d-feeder-for-mk8-drive-gear). Those aside, I have to say this is probably the best feeder that I've bolted on, and I've tried many over the years. Thanks!
hi @SolidPrint3D ! thank you for sharing - i need to modify it a bit because i want to install it at an UMO with an MK8 drive gear, can you therefore maybe share the STEP files with us? thank you!

- Printed on:
- Ultimaker 2
- Result:
- Very professional design. Thanks very much. I didn't like the need for buying new screws so I cut off the bottom 2mm in Cura and made the housing the same thickness as the standaard feeder on the UM2. Set the top/bottom to be the same as the number of layers remaining so that the remaining shell was at least a 100% solid fill.
- Feedback:
- Couldn't get the ABS to stick while I was printing this so in the end I went with PLA instead. Unfortunately that did stick to the ABS juice like a vise and I had to literally rip it off. the surface looks rather scruffy because of that, but it works just fine. Cutting off 2mm on top and bottom gave some extra openings in the housing. Or rather, it gave a 1 layer fill that broke away. Still, I preferred to use the standard screws.
