This a replacement ring shooter for an old tabletop combination game set that I inherited from my grandparents. You can still buy similar sets (such as this one): https://www.homedepot.com/p/CARROM-Game-Board-100-00/311687404

Some sets come with cues, but it is more fun with these rubber-band-powered shooters!

This is specifically designed to fit the rings supplied with my set. If you have another set with rings of different dimensions, you can contact me in comments and I may be able to adjust the dimensions to fit your rings.

Photos show side-by-side comparison of the original shooter beside my redesign. No support is necessary if you print with the flat top down on your bed (your slicer may complain about overhang, but don't worry, it prints fine).
