I made this ashtray for my Friend who loves Porsches. All the parts do fit on a standard 220mm build plate but I recommend printing the lid separately and with a raft to avoid warping.

The wheels and body support M4 bolts and inserts (I used M4x20mm)

For surface quality I printed at 0.125mm layer height but you should use the settings you find best for your machine. Supports should be placed everywhere for the main body. You may want to add some support blockers around the wing arms as it can make it impossible to remove the supports later. The wing, wheels and wiper blades all print fine but can be a little brittle so be careful with those! 

This print will later be painted with high heat enamel to protect it and make it useable as an ashtray.
