I did this. Sent him to California with some family friends.

Thought this was LeVar Burton.

Not quite sure what your concern is with the top fill pattern. It is a load-bearing part, so it kind of needs to be the way it is to retain the part coming out the other side. As far as the extruder exiting the perimeter of the model, I would remind you of the possibility of printing more than one model on a build plate. Although, I hadn’t yet considered trying to print only one to see if it still happens, as a troubleshooting approach. I’ll try that later, to rule out the possibility that it’s being mechanically pulled off by an extruder transport move.

It’s enclosed

I’d considered raising the temperature a little to get the perimeter to stick better to its neighbor, but I wasn’t sure if hotter printing would worsen the thermal contraction, which is what I was originally suspecting was happening. Nothing ever pulls off from an outer perimeter, it’s only inner perimeters of empty loops or holes.

It’s both first layers and higher. No pattern I can find. Bed adhesion is definitely fine, I haven’t had a single lifted corner since I started using the SuperTac plate.

It’s like Clark Kent’s glasses, but a crop-top.

No.
