Y Axis Bearing 11mm x 5mm M4 for CTC Replicator Flashforge

thingiverse

Updated version available since April 22nd, 2016! Hey folks! I remixed one of the many y-axis bearing-blocks out there to fit M4 Screws (the original uses M3) and an 11mm x 5mm roller bearing each, used for rollerblades or skateboards. The bearing-blocks need roller-bearings with 4mm or 5mm depth, but it's quite obvious that bearings with more depth will fit too, they just extend a bit from the surface. It doesn't really matter. The M4 nuts are self-securing due to the shape of the inner "chamber" for the M4 nut. Very easy to install. You need to print 4 in total. So you need... 4 bearings with an outer diameter of 11mm and an inner diameter of 5mm (depth doesn't matter much) 8 M4 nuts and screws in proper lengths (10mm or longer) (optionally) 4 short M3 Securing Screws for the bearing. Normally the roller-bearing is a tight fit, so you don't need them. Note: The drill helper plate is optional to print. Just for orientation. Print the helper if you need some instructions where to drill holes. Don't forget to double-check if the space behind the wall you drill a hole in is not occupied. That's a stupid hint, I know, but I was nearly that stupid. The bearings improved the stiffness of the y-axis a lot. Much less wobbling on fast prints. Have fun! Print Settings Printer: CTC Dual (Replicator Dual) Rafts: No Supports: No Resolution: 0.3 Infill: 25% Notes: The white one is PLA and it's recommendable to print with when you don't heat your build chamber. However, if you want to heat your build chamber, then I recommend printing in PETG or ABS. The yellow Y-axis bearing was printed in translucent PETG Yellow from ESun at 240°C.
