Gridfinity Refined - Ammunition Display

I printed out some historic cartridges to display, but got annoyed because they kept falling over. Since I use Gridfinity for everything else, I thought I would make something to use for this. There are three sizes:Pistol ammunition - 3 per 1x1 Gridfinity square, can fit up to .44 mag and .50 AERifle ammunition - 3 per 1x1 Gridfinity square, fits all standard rifle ammo.50 BMG - 1 round per 1x1 Gridfinity square, could also use for shotgun ammo etcI printed these with 10% infill as they don't need to be strong, they are just for display Gridfinity Refined is a updated but backwards compatible system that adds in the ability to connect plates together and has screw holes that allows you to more securely attached your inserts to it. It was designed by https://www.printables.com/@grizzie17 and the original spec and files can be found at https://www.printables.com/model/413761-gridfinity-refined This particular model also started by using the OnShape from Scratch bins here https://www.
