The file 'Recirculating Linear Bearing 20×20 Profile 3D Printer Model' is (stl) file type, size is 398.6KB.
Another model of my linear bearing, this can fit on the 2020 alluminium frame or above, print 2 and screw together. Always print vertical and with low resolution. Work with 6mm sfere, airsoft bbs can be used for testing.
UPDATE
I correct the internal rail, now work better with 6mm balls
