This tool has been designed with the aim to have an handy tool to fix racing quad props nuts and Video antenna SMA connectors.
Open side is for Antennas while closed one is 10mm exagonal wrench, suitable for racers motor.
I found this tool a must have in my field box.
After design with nominal dimension I made a print test with my prusa using ABS and I realized that the size come tighter tha the nuts due to thermal shrinkage of this material.
After one more test I found that 107% is the ideal scale to be applied. If you print with PLA you have to find the correct scaling factor that should lies (I suppose) between 102% and 104%.
My settings for ABS are:
Layer height 0.2mm
wall thk = 1.2mm
top/bot = 1.0mm
Infill = 35%
This tool can be used directly after printing or if you prefer a better look some acetone vapour can improve the surfaces
