Radiator Drain Wrench

I designed this because the radiator drain on my Ford truck is awkward to reach and operate. The first wrench was for the original radiator, and fits a 3/4 inch hex head. When I replaced the radiator, the replacement was made by Spectra, it had a wing head on a 12mm shaft, so I redesigned the wrench. Later, I made a second version of each with a longer shaft and larger wings. All four are included here, so print up whatever you need. I printed them with a 2.5mm shell for extra strength, and they hold up well. It prints vertically, so definitely use a brim.
