My stock MK3 R2 Y Belt holder has started to slip teeth. Can I just print the Y Belt holder and have it work okay with the original idler and motor mount as shipped/delivered from Prusa, or this needs to be printed in a complete set (motor mount, idler and belt holder?) I don't want to make anything worse :)


It will work better then the original belt holder design

Thanks, My belt started to skip through the bed part yesterday so I'll print yours and zip it.
I have this tensioner already https://www.thingiverse.com/thing:2786671

Gee, just use a toothed idler pulley same as the motor pulley, keep all aligned and //. So obvious ! One of the first mod I made.

Use the bed belt holder as well , The belt alignment height is tweaked for perfect alignment (zip ties recommended )

As I wrote, I don't use ANY OF THIS. I made my own simpler bad attachment and a toothed idler leading to a BETTER, SIMPLEr solution as all is in lie and // !!!

Great for you
