Bolt Handle

Bolt handle for a 13mm bolt.
An extra nut tightened against the bolt head is used to give extra support to the bolt.
Bolt size can be changed using the SolidWorks file.
I designed the model to be tight to make it stronger so the bolt will need to be installed into the model using a hammer.
I printed the model at 100% infill to make it strong and so that the bolt wouldn't ring out.
