three part closed lid self extinguishing ashtray
thingiverse
A three-part-thing. Consisting out of -a cup, -a top for the cup -a lid for the top could be used as insect-trap... Or as self extinguishing ashtray. Due to a lack of oxygen, your sigarettebutts will go out. Colorfabb PLA works on this scale, a larger scale means more oxygen, and more time for the 300°C sigarettebutt-end to smelt through the PLA. Still best printed in ABS or glass transition temperature of +90°C. in that case, use closed printers , bed adhesion glue, heated bed, and Brim. ABS prints of this design tend to shrink, curl, warp. Nylon works best(taulman3D) under flex settings(no retraction)
