Someone in a swedish 3D printing group requested a container for her friends ampoules that she uses with her (she has diabetes), so i made two different versions depending on what they decide on using. Its a basic cylinder with a divider and two lids (one for clean and one for dirty ampoules, clearly highlighted by a biohazard logo on the lid) while the compartmentalized one is made to hold 5 ampoules on each side in slots.

The holes in the compartmentalized version is 18x8mm and is made for models similar to the SoloStar 5x3 ml ampoules, if requested i can post a .STEP file to adjust measurements to your liking.

UPDATE: I added a slimmed version with space for 3 ampoules total (still the same model) that goes in a single tube, you have a clean end to indicate the clean ampoules and then you load the bottom with the dirty ampoules (indicated by a biohazard sign on the side and on the lid). You can apparently tell by visual inspection that a ampoule has been used on the container itself.
