Coin holder - different sizes

I've made coin holders for polish grosz (1, 2, 5, 10, 20 groszy). There's a view port with ruler, it's pretty accurate (I measured stack of 10 coins by precise caliper). I also generated some cylinders as a filler, to prevent coins movement, if the box is not full. 

My model is parametric, so I can easily generate models for different currency, if someone would like to. I just need internal diameter of the box (in my case I added +-1.5mm clearance to coin diameter) and height of 10 coins stack. 

Print tips

• no supports
• variable layer height is nice for bottom part (for digits and ruler lines)
