Summary

This enclosure is for a curved deck. There is a slight bend as you can see. I highly recommend to print with PETG because the ESC can get hot when you ride the board for a long time.
Print time with PETG with tree support was around 11.5 hours with these settings:
nozzle 245
bed 80
quality .3
initial layer, no fan. 30% afterward
speed, 20 mm/s on initial layer. speed 40 afterward
