Printed in petg with 4 walls seems to be holding up so far.

This loom has a c2c of 1cm and a peg radius of 4mm. The resulting piece was 10cm wide using bulky yarn number 5.
Printed on Makerbot Replicator+ at a library.
Had to use a raft this time (because makerbot sucks), but otherwise printed perfectly fine. Took about 3.5 hours.
