instead of buying trash bags we reuse newspapers to collect kitchen waste over the day. these are welcomed in biodegradeable waste and compostable. they would end up in the trash anyway and in this case we spare cleansing water for any other collector option.
there's a particular folding technique to create paper pags (not mine but shown in the pictures). due to their shape we were in need of something to keep them upright. a planter was not a reliable solution so i designed something more fitting. behold the trash(bowling)ball!
this model fits newspapers sized 35x51cm, scale to your needs. diameter of 180mm most likely fits most beds.
printed in petg. 3 walls are enough with 10% lightning infill which is almost hollow. add tree support for the grip.
