CNC 3018 Supports for Leveling

Having the wobbly CNC3018, I made these mounts to CNC stabilize with millimeter precision.
Wanting to be even more precise you could modify the rear support, since the Z axis is positioned at 31.5mm from the rear bar.
The holes for the nuts and the bolts have been made slightly smaller than the nuts and bolts themselves and it is therefore recommended to first heat the nuts with boiling water to facilitate the fit in the PLA
I was inspired by this idea of DIY3DTech (https://www.thingiverse.com/thing:4266616)
