Traxxas X-Maxx Nut Tool

For me the original X-Maxx Nut-Tool did not fit, so I optimized the spaces for 3D printing.

But thanks @NothingSpectacular for the initial design.

Update: It does not fit for the E-Revo, therefore renamed back to XMaxx Nut-Tool. I'll provided a complete new version that fits all: https://www.thingiverse.com/thing:4950009
