OldHam generic with m3 inserts, Z banding

i made this oldham with a lot of modifications from other options online, first thing i did was designing the space for  m3 inserts as i think it's better than nuts, second thing was making the middle hole bigger, so the movement that the axle can move is way bigger, i think i improved about 100% more movement than most oldhams on the internet. you could move up to 3.5 mm each axle.

maximum angle is 45 degree, but there are big bridges, so print slowly. and use support on build plate only.

i use 5 walls and 80% infill but up to you. 

print bottom and top twice per axle. 

it also has two files, one with holes to make it easier to lubricate the plastic and the nut on lead screw and plugs to protect the hole so it don't get dirty inside, and one without any holes. 

the tolerance is really low, so it doesn't have any slack, you might need to 
sand a bit to make it move freely, but if your print it slow it might not need it. 

there is also a version with less precision, about 0.5 mm more slack, i don't advise it, but if your printer does are not printing it correctly it might be a better option, you can print it to make your printer better and do the other one after. 

i also added a plug, in case you want to close the holes, so dirty don't come inside, i will not use myself, but test it out, and works to plug the holes and do not fall down

for lubricant i am using super lub dri-film lubricant with syncolor (PTFE), but i am not sure it's the best option. 

follow the steps to assembly it, the most important one is step 1 and 2, if you mix it up, the top/bottom will not slide inside main body with the nut connected to it.
