I wanted a endcap for my HEX screwdrivers from Aliexpress.

First I printed model https://www.printables.com/model/418521-hex-screwdriver-cap but Unfortunate, my screwdrivers are a bit smaller.
I could just have scaled it down,but instead I decided to make a design from scratch.

The hole diameter of my screwdrivers is 10.8mm.

Update: I added a hexagon design so the screwdrivers won't roll off the table anymore. :)
