Modular Quiver

2 Round ammo quiver that, with small alterations, can fit any caliber 45 and under. 

Actual quiver should be printed in PLA+ or better. Best print orientation is as shown in photos, with the flat side of one tube flat on the bed and supports for the rest.

Inserts should be printed in soft/squishy filament. I used TPU. No supports needed.

Insert Blank STEP file included. Simply insert a hole in your favorite CAD program that is slightly smaller that the case diameter of the caliber you wish to use. I've found 0.1-0.15mm smaller than case diameter works well.  You can also fillet the inside edge about 2mm to make inserting the rounds easier but it's not necessary. 

I've included 45-70 and .357 Magnum STLs as examples. 

Only requires 2 standard M-Lok screws/nuts for installation. Once the quiver is installed on a rail, the inserts can be installed small end first in the tubes. They pop in and the small lip on the other end holds it in place. But they are completely removable and re-usable.
