mini screwdriver

I needed a small screwdriver for screws inside the rims of my kart, everything i had was to big.So i designed my own. works like a charmyou can even switch different small hex(6mm) bits.the ring is moving free, so you can hold it an twist it at the same time. for the assembly you need 2 M3x8 screws I set all the walls, bottom and top layers to 5, whitch makes it very strong i also created an insert for a rugged box where you can store 5 mini screwdrivers, see my other modelsBoost Meplease boost me if you print the model, thank you in advance,
