Thats not an official accessoire for Elotrans products. I just created this as a joke.
There are two versions. The normal one fits a 10 (maybe even 20) pack of and additionaly some other stuff or medicine.
The symmetric one is made to open in half / 10 pcs of elotrans box. Please print the TPU rings accordingly, if needed.
You will need 8 M3 screws for the hinge/latch.
