Linear Bearings, IGUS Style !!!
Derived from
Description
But !!! Instead of changing all the carriage ... switching to PLA "old style bearings", I designed "ready to print" Bearings, There is Three equivalents, LM6UU, LM8UU & LM10UU !.
They are all the same size as original bearings :)
Tooth thickness is made to print well on 0.5mm nozzle, altought a LM10UU 0.35mm will print really nice :)
More tooth is better :)
Instructions
First thing ... simple insert the printed bearings in your rods, and "play with them" rolling/sliding, to ensure they slide well, you can also lubricant them !! the lubricant will stay between tooths !!!
Simply print slow with 0 infill and 3 perimeters at least.
Hum and ... that's all I think :)
Tested them on my X & Y at 120mm/s infill and 200mm/s travel they do not fail :)

Any chance you can make one for a 9mm rod? I accidentally purchased that dimension from McMaster and would love to be able to use it!
Hmm, i would love to use a few LM12UU's. Think I could just scale a LM10UU? What would the scaling factor be? (Save me some guess-n-test) :-)
Made one and used it as a quick fix on Huxleys x-carriage upgrade.
Still missing another "real" LM6UU. In meanwhile finding one a quick fix that worked!First I cut it in half and second cut to make out a sector possible to fit it in without need to take linears out. They do not press tight but takes most of the wobble out. There should be a close up picture about this in "made one" section.
Did you use the scad of the original toothed bearing? Could you please post the settings you used?
Thanks
I printed a bunch of these and they work great.... mine printed a bit tight so i used a piece of allthread and scraped back and forth a bunch tell the fit the rods smoothly and snug.... they are working awesome
I cannot get the 6mm STL to slice. It says that the model is not manifest. Fixing with meshlab didn't do the job (but I am no meshlab expert). Any ideas?
I'd suggest white lithium grease as a lubricant. WD40 isn't a lube, and will actually eat up parts over time.
Is ABS working?
ABS is an elastic polymer. PLA is the better of the two to make your bearings.
Very nice design!
Rather use Q20 if you can get it where you live

I think ABS will squeeze a bit more than PLA and tight more but let's try I have no more ABS in stock yet.
Wd40 is generall considered evil as a lubricant, as it is a digestive, how long do they last?.

What do you think about "3-in-1 Oil"? It's a bit smelly, but has low viscosity. I'm curious whether it would soften PLA or corrode stainless steel.
