My first hobby design, ashtray with a lid that closes the cigarette holes if you turn it 90 degrees.

AshtrayLid with Holes are for the Inserts if you want to print it seperat, → tight 1 : 1 with the holes, wiggle → 0.6mm wiggle room 

i printed it with a fdm printer on 0.1 mm with 15 - 20 % infill
