I needed an easier way to count coins specifically quarters in in quantities of $10 and $50.
I found some on thingiverse but none quite met my needs so I used tinkercad to make my own. loose enough that you can dump coins on top of it and wiggle it around and they fall in and as long as a bunch don't fall in sideways at the same time a jiggle will right sideways coins and the hole is big enough on the bottom for my larger fingers.
I need $50 bags of quarters so I put 5 together. I also rubber band two of these together fill them then sep and dump into the bags. I also included a single roll for those who want or need that.
simple cylinders with cuts
