Based off of the 50 BMG Wikipedia's dimensions photo [here](https://upload.wikimedia.org/wikipedia/commons/thumb/0/0f/12.7_x_99mm_NATO_dimensions_converted_to_millimeters.png/1336px-12.7_x_99mm_NATO_dimensions_converted_to_millimeters.png).

Can be used as a keychain with the loop in the bullet, or in the bottom of the casing. Alternatively, as a ornament for  your Christmas Season.

 

You can also use PrusaSlicer to add a cut on the keychain model right where the casing meets the bullet to print them in separate colours as I have in the photo. You can also add connectors to easily attach/detach. Could also print the bullet with a ‘tip’ of another colour like red/black/green for different types.

Used the following filaments:

Casing: AMOLEN Silk 1.75mm Gold

Bullet: AMOLEN Silk 1.75mm Red Copper

Based on my prior Calibration Cube Keychain, this model features a slightly thicker loop-bar as the prior one had a tendency to break being so thin. 

It also changes the placement of the loop to be in the top-left corner so that when attached, the lettering is facing towards others. 

Calibration Cube Keychain v2

Loosely Based on Jagahati's model [here](https://www.printables.com/model/594625-coffee-cup-water-bottle-expander-for-vehicle-cupho). 

I wanted a similar one that would fit a Hydroflask 32oz with a silicone boot. So I remade it and enlarged the opening to 96.5mm wide. 

Should fit most cupholders.

(Boot + bottle is 94mm - Normal bottle is ~ 91.5mm) 

Did 25% Infill
Took 113grams of filament, and about 12 hours on Neptune 3 Pro.
