nylon-based filament to get enough stiffness - though the material is quite brittle
I'm curious to know more here. Sure, it doesn't flex like PETG, or even what little flex there is in PLA, but for things like clamps and static objects holding a load, I've seen good results. Nylon tools I've used—made by the guy who got me into printing—last FAR and AWAY longer than PLA tools I've printed and far less brittle. The stank and general PitA nature of ABS setup wasn't worth it to us. Getting it done by someone else? another story, perhaps. Also, FWIW,
injection mold ABS is much stronger than FDM:
The redesign is, as was stated, a
test, and joshc knows that. I'm not an engineer, I just like to make things
I don't have high hopes for PLA, but a nylon would be a step up. The original design was
designed for aluminum, so...
Also, I'm curious how much heat a IIfx actually radiates through the case. Anecdote: I printed a (PLA) shower head bracket replacement and it's been installed for over 3 years now with only a small chip on the corner falling off (an exposed impact point for the head) after daily use in a hot and humid environment.
Yes, I know PLA will DEFINITELY deform. I printed some columns in black PLA and left them in the sun for all of 10 minutes in summer while I went to fetch something and they were already drooping...
