MiniQuad Prop Wrench

The current design is slightly too compact and V2 is slightly too spacious, so adjusting it up or down by about 1% will likely yield a more ideal fit. I'll address this issue promptly. A prop wrench can be used for added leverage on the motor nuts. V2 has a marginally larger hole to accommodate cases where the standard one doesn't fit, but it may also be more susceptible to stripping.
