I'm in the process of turning my rapman into a chylldman..
The bed holders work great! There's still a very slight pattern visible but quality is much improved.
Now printing your other corner sets. Thanks a lot for your designs!
Looking good! Glad to help :)
Any remaining pattern is probably mostly caused by an imperfect Z motor gear. Print my custom Z gear and see if it rotates perfectly still after tightening the grub screw, if it doesn't, shift the grub screw hole a fraction and print again. Sounds tedious but it's worth it!
