Carisma GT24 4.5mm Wheel Nut Wrench

This is a small wrench I designed to remove the wheel nuts from my Carisma GT24 R/C vehicle. The plastic wheel nuts on my car are 4.5mm in diameter and the small wrench supplied with the car was not long enough to get the nuts out of the wheels. I could not find a 4.5mm deep socket to use, so I designed this to use instead.

Some people have said the wheel nuts are 4mm but calipers showed mine at 4.5mm

Please note that I printed this standing straight up with the cross section at the bottom
