Nylon Linear bearing
by MakeALot, published
Direct replacement for LMB6UU (3/8") Linear bearing as used in Thing-o-Matic mods.
Buy some 3mm Taulman 618 Nylon (it's brilliant), print some of these at:
100% object infill, 0.29mm layer height, 0 extra shells, 245 degrees C, bed 50 degrees on a PVA painted kapton bed.
and use them wherever a design calls for LMB6UU 3/8" ID Linear bearing.
I'm expecting them to last well, but even if they only last a short while, at $20/lb (454 grammes), each bearing cost $0.10, compared with $5 for the LMB6UU.
BTW, the Nylon does not de-laminate, so I'm going to print some linear mounting blocks and upgrade all of my ToM carriages.
