What is it that you’re modelling here? (are you reverse-engineering the geardrives or something?..my noob brain can’t work it out)

down to the .1mm range yeah. I have skipped the slew bearing and o ring for now, not hard to add.

@Boardnamics IS THAT SLEW BEARING USER-SERVICEABLE? oops caps

oh I imagine you could roast the thing to get it out…

Im guessing just for fun, or do you plan in 3D printing some parts?

I want to use the gearbox and also just some of the components for other purposes like the Electric freeboard projects. At least the pinion gear will be useful for sure.

can I ask, how easy would it be to model BN style press-fit kegel pulleys at 60T (for 3D printing)? Would be awesome to be able to have some large pulleys for bergs that are using @mishrasubhransu printed berg Kegel hubs…unless @Boardnamics himself plans on releasing any (though I don’t see a reason for that happening)

Just opened my box from Black Friday :eyes:
often I don’t read everything I should

I ordered this: https://boardnamics.com/product/dual-m1-drive-220mm-hangers-kit/

Do the hangers not come with axles?

But it’s soooo short! Dammit I don’t like it but now I want one…

Is this an accurate representation of how much space remains between two 6374 motors mounted on the BN220 hanger?

I’m wondering because I’m designing a 3Dprinted spacer that will allow me to leave a little more length on my motor shafts while still being compatible with the gear drives.

Guys what loctite should I use for the axles? And for the motor screws/screws inside-outside the gear drive?

Mine and B264’s are JB weld’ed in forever I also used blue and or none and it was fine.

West System 650 epoxy or JB Weld 8265-S Original Steel epoxy

I don’t know what’s recommended but I usually use Loctite 290. But this may not be best

3DS recommends Loctite 648 (aka green loctite).
