I did not see something like this, and I needed it so I made it. Why ? Because even though my side SH works well, it inducts too much vibrations when I print at over 30mms, which of course results in bad ghosting. At 80mms it even does waves lol.
What is needed :
Xtreme V wheels x 4 (plycarbonate is the best)
625ZZ (metal seal) or 625RS (plastic seal) bearing x 8
Precision shimes (washers) are NOT necessary.
You can find preassembled wheels at aliexpress, like this one : Type A
But I recommend to buy wheels and bearing separately, so you can choose 625ZZ bearing (metal seal) like this one
NOTE : There is a sample test file included, print it before wasting material and time. The wheel (in fact, the bearing) will take its place when you'll hear "clic". You do not want to have loose (play), but you should be able to remove the wheel without breaking the axis. It must be strong enought but not too much at the same time. Scale the meshes by increment of 0.005% if needed.
