Mugstacker - Cup Stacker

This was my first created model, due we have so many cylindrical mugs which cant be stack very well. So here is the solution, the designe will fit to the most mugs I have tested so far. I have try to print it with out support but have no success may be you can do it with out but I don't recommend to do so. Used Material: Bambu Basic PLA (green) Bambu Support for PLA
