airsoft shotgun shell holder (fully parametric, link in description)

thingiverse

Human: link to fusion360 parametric file : https://a360.co/2sFp7gz Tested with cyma and ASG shells (ASG are a little bit larger than cyma) #### Features : - **Fully Parametric** : You can adjust about anything to fit different calibers and tweak some aesthetic settings (within reason) - **Quick Insertion and Removal of Shells** : Thanks to chamfer and full circle on top - **Sturdiness** - **Good-Lookingness** : There is an end stop so shells do align well + smooth shapes #### Things to Know : - **"Short Retention"** : The shell is only retained when fully pushed in so it has not a great "range" of retention along the holder - **Tight Tolerances** : Due to the sturdyness of the design, there is not much flexing. This means you have to take extra care of your tolerances. If needed, you can use scaling on your slicer or play with the parameters in the Fusion360 project. #### Printing : I print them with no support (bottom on the plate), also I use a quite large brim (15mm) with ABS. I recommend printing just one to check dimensions first (not all shells and printers are the same). I also strongly recommend some kind of smoothing (acetone and/or sandpaper) as the constant rubbing can scrap your shells stickers.
