@dmols - Nevermind (prob printing in ABS would be fine) I'll adjust gears' inner diameter using sketchup. I think we can delete all the spammy comments below. In essence my problem is that inner diameter of gears is too big and it causes a bit of backlash. People be aware of that. Also I used Ultimaker Flex-PLA which does not have much grip (like NinjaFlex) so I advise others to do not even try if You do not have soft and grippy filament.

Sorry for spamming this one, but I tried assembling resized feeder onto my UM2 and there is too much space between motor shaft gear and other gear. @dmols could You please post gears' source files, so I (and maybe others) could resize their IDs.

@dmols - I printed everything on 0.985 scale in PLA and now everything fits about right. Motor mounting is a bit difficult but I guess I'll be fine.

@dmols. Problem is that the PLA gears Inner Diameter is a bit too big (8.2 instead of 8). So there is some free space around bearings, which (when combined 3 gears) allows backlash. Thanks for advice about PTFE lubricants (btw. PTFE = Teflon) Do you print gears with ABS or Nylon?

@dmols - I printed in PLA (not the best quality, but pretty good one). I assembled it on spare motor - everything fits tight, except there is some freedom with bearings (as I've mentioned 8mm bearing in 8.1-8.2 holes). As a result there is some small wobbling (back and forth) with gears (because of larger ID) , I'm not really sure if it will be a problem while printing. Did You oil gears (light mineral oil or synthetic grease?) to reduce friction or no?

Hi there, I have printed whole assembly, but for gears, I get 8.1-8.25 ID, when not completely assembled it feels that it has some free movement. However the body seems to fit spare motor nicely. Should I reprint my gears with -1% scale or should I just assemble it and hope that it will be nice and snug.
