Screwdriver handle

I designed and screwdriver handle to replace the original one that broke on my (first ever) screwdriver. My name is also written on it for customisation, but it can easily be deleted from that surface and replaced with yours.
Please note that the shaft of the screwdriver is 3mm in diameter, so before printing measure yours and modify the design accordingly.
The assembly of this part to the shaft will be done by heating the metal and trying to insert it as straight as possible.
