Kidney stone catcher

Catch that pesky little stone that caused you all that pain.

Mount it on the wall to remind you to drink more water and do whatever the Doc told you to do, to prevent further stones.

The sieve is small enough to catch any size stone that will case you pain, but big enough to allow sufficient flow. 

You can change the hole size by increasing or decreasing the Sparse Infill Density of the Generic Disc object  in the 3mf file.

Hold the little tab keeps your fingers nice and dry. It's even left and right hand compatible.

It's big enough for most, unless your a bull or an elephant.

The oval version fits better in your pocket
