Ultimaker internal axle end
by coyote69, published
This thing goes in place of the original wooden axle end of the ultimaker inside the body.
It can hold the 2x M3 nuts so it's a lot easier to fix the part (no more need to hold the nut with a twizzer or nut holder).
The hole in the center is also a little wider in order to limit friction on the bearing.
Works great in conjunction with thing 54075 for the outside.
Print with 0.8mm wall 20% infill.
Push 2x original ultimaker M3 nuts. It's a little hard as the opening is really tight and you will need something to push them in.
