A customizable thumb spanner/wrench design that fits on a keyring. I've got a few examples of this file - details below.

22/05/2016 - Customizable Version Added Unfortunately I can't get the text rendering to play nicely with the customizer so I've removed it from this version. It is still in the file with some instructions on getting it working -- the modules and variables are commented out though so if you want something with labels you probably want to download the .SCAD file and go from there.

22/05/2016 Uploaded an 8mm version (M5).

19/05/2016 Added a double sided propeller spanner for keeping handy on a key-ring so that it doesn't go missing when needed. It is designed to fit M5 and M6 nuts. The M6 fits the Emax 2204 2300kv motors.

M5 = 8mm. M6 = 10mm.

(Flat to flat on the outside of the nut/bolt.)
