KvR's Compact Extruder with Direct Drive
by Printing-3D, published
Spring, MK7 drive gear and 608ZZ bearing used to get the correct pressure on the filament. First tests with 1.75mm filament gives excellent grip.
Next step is duration testing. Keep you updated

I used a din 913 M4*16 bolt.
The printed hole I drilled to 3.2 mm and used an M4 thread drill.
Hope this helps! Otherwise, just let me know.
Hi, I'm currently trying to adapt this to a new hot end I'm working on. Just curious as to how you're mounting the bearing. I don't see anything that serves as an axle anywhere.
