Width may not be an issue if you double stack

Did you do a stress analysis on those? Would be kinda interesting to see, because the area where the bushings go thins up quite a bit. Also they look reaaaally nice.

thank you!
yes, i made a lot of simulations, and this design is probably the 17-20th iteration of the initial design, so don’t worry the area between bushings is not to thin

b264 · December 30, 2021, 9:00pm

My very first thought was also that the area between the bushings was too thin

Linesflag · December 30, 2021, 9:00pm

Very cool! Would you mind sharing those? Would be totally okay if not, I’d just find it very interesting.

Just curious… But aren’t you worried of the plastic melting? I know that if you reach melting temperature, you probably have bigger problems but pla goes soft at like 50 or 60 C°

glyphiks · December 30, 2021, 9:08pm

Thats petg, and not really concerned about melting. As you say, if thats melting, i got big issues

Linesflag · December 30, 2021, 9:20pm

PETG becomes soft at around 85°C, which is also the throttle threshold of most ESCs. But yeah, you could run into very slight deformation in the summer.

Doesn’t Australia get real hot in the summer?

You should make the top of the kingpins below the hangar so that you can grind on them

glyphiks · December 30, 2021, 10:16pm

Haha yeah but fuck riding in crazy heat

janpom · December 30, 2021, 10:31pm

@glyphiks What kind of supports sorcery is that? Did it come out as a single piece just like that?

glyphiks · December 30, 2021, 10:40pm

Haha yep. It took a while to get it dialed and a fair amount of technical support from @Scepterr and the lads in the 3dp group on telegram, but pretty happy with where its at!

Check out concentric support top layers

Man those balance wires look like an old school PCB with the big swoopy traces. Looks nice, no sharp angles or kinks in the wire

Battery_Mooch · December 31, 2021, 1:59am

Ahh……the “good old days” of laying out the traces with Bishop tape and photo etching the boards in a tray in the bathtub. I miss them not!

mr.shiteside · December 31, 2021, 2:00am

Big 'ol dunk in the tub of ferric chloride?

b264 · December 31, 2021, 2:26am

I do NOT miss ferric chloride AT ALL

Dunkan · December 31, 2021, 3:29am

Aw common it was fun! I remember making PCBs in tech class it was fun
I think

DEEIF · December 31, 2021, 3:54am

That on the Prusa? How’d you tune it? My supports suuuuuuuck using prusaslicer
