This is a remix of the original design with changes to the bolt depth to allow for M3x30mm bolts, as well as a chamfered base for angled mounting. I have also created a cutout for an M3 hex nut on the base so the enclosure can be mounted from underneath to make mounting easier. Additionally, the lip of the screen enclosure has been raised for more protection and adequate fitment. The cutouts for the peripheral ports on the Pi have been increased as well. 

This is printed without supports, and I have printed it with a 0.6mm nozzle, and all parts were completed in under 4 hours.
