I separated into 2 version:
In this alternative version the stubby body is a single color (You can still do color swap. Nobody can stop that…) and the cap is fixed so it's simpler to print.
The accent ring is printed separately. You need to add a pause to the correct layer and put the ring mid print.

The maximum supported length for the bit extender stem is 6 cm. Or 9,5 cm in total. It will protrude from the inside but don't worry it will not interfere with the bit holder.
The author marked this model as their own original creation.
