Simple triangle shaped puzzle ashtray, made out of 3 pieces/puzzles.
Beside various color combo, there are two hole sizes, small 6.5mm/0.25in (for cigarettes), and big 17.7mm/0.69in (for a cigar). 

Make your combination!

I used ABS since PLA is not so heat friendly, also ASA would work.
No support needed. Easy to assemble. 
In case of printing in one color only, just clone the model.
