Thanks!
I printed in ProtoPasta’s High Temp PLA.
This in itself was challenging, so I designed the enclosure to be as strong as possible:
There is a 2° draft on the top of the enclosure, which lets it print at a 2° angle. This angle slightly off-set-tilts the layer lines when printing which directs the plane of weakness into the mounts and deck but more importantly providing substantially more surface area for layers to bond to each other.
