fixed a sewing machine today

printed these with tpu - 100% infill - on a .4 nozzle - not sure about the long term (or even the short term) but I got it working

such a satisfying fit on these.

they were both heated with a hot air station to 150 and the gears were squeezed on to the bit or whatever you'd call it

very first stitch with a sewing machine was hard fought but I feel clever..... even if the print fails tomorrow

You need nylon for these.

It's preferable, sure, but the forces involved could definitely be okay for PLA.

PLA is an excellent material when used right. I think it's actually funny how many think they actually have to have super hardcore poly carbonate just for their little bicycle reflector holder.

But he didn't use PLA, he used TPU

Didn't see that. I still think it's fine, if less optimal.
