Travel Sharps Container - Prefilled Injector pen

I've been looking for a travel sharps container for prefilled injector pens for a while now but the only ones that would take a full sized pen are 0.5l bins and far to big for air travel.

The model consists of two parts and screws together and there's enough tension to prevent accidental opening. 

I printed this on a MK3S with MMU2 with a 0.4mm nozzle 0.2mm layer height 20% infill with no supports. 

Filament 1 was Prusament PETG Prusa Orange and Filament 3 was Prusament PETG Jet Black for the Biohazard embellishment

I've included GCode for MMU and MMU Single

Also included are the Fusion 360 files if you want to make some adjustments. All parameters are done as variables. You may need to change the thread setting to match the innerDiameter setting.
