308 Ammo Tray
thingiverse
This is a very basic reloading block for 308 and similar diameter cartridges. I made it fairly short to take up less space so the finger slots on the sides are a little on the small side, but they work fine for carrying the tray around. The holes are made to be fairly tight to prevent the wobble you get from typical universal blocks, so you may need to do some light sanding depending on how well your printer can keep spec. Hole diameters are supposed to be 13mm and a 308 case at the base is roughly 12mm so I'm hoping this accounts for any discrepancies between printers and various settings. Please let me know how it works for you.
