Actuator foot weakness - stage Y-axis actuator broke :(

I’m following up on this to see if anyone got anywhere with a PLA test foot.

I’m currently trying to specify the PLA requirements for building quite a large number of units, and so am quite keen to get this right! My initial thought was to go for a Sunlu LightGold, which is a PLA Silk, but the comments about knowing just what is in the silk and the vagueness of manufacturers’ descriptions of their ingredients is making me nervous.

So any models I can use as tests, maybe involving some gentle destructive testing, to put some ‘strength’ numbers on various brands / colours etc, would be great.

If not, I’m happy to do the cad for a test model, but I could do with some inspiration for its design (my skills, such as they are, lie elsewhere). The need to consider twisting is particularly interesting.

Thanks!
