Keychain screwdriver

Needed a handy screwdriver for my keychain but couldn't find anything cheap and good on Amazon. Then I realized it would be a good first object to design as I learn solidworks.

I printed in ABS, no supports or anything. It fits a double sided hex screwdriver bit. Hope you like it as much as I do.

*Let me know if the fit is alright. I also updated the keyring cap and thickened the hole to 5 mm (from 2 mm), because mine broke.

-EDIT 1/30/17 added a thicker keyring hole and uploaded the bottom cap without the hole
