Dremel CNC - Anti-backlash nuts mod

Since I did not find any version of Dremel CNC that would be ready for intallation of anti-backlash nuts (they are bigger and longer than simple lead screw nuts), I modified some designs I liked and here they are.

There are holes for installation of one 300 mm* long piece of 20x20 aluminium profile on the X axis to make it more sturdy.
The X axis carriage is also modified with more space on both sides in the lead screw area so that you can gain the X axis range that would otherwise be lost because of length of motor couplers.

I attach STEP files as well so feel free to modify my mods :D

*This profile can be longer depending on the length of profiles you used on the base to connect the two longest profiles. In original Dremel CNC profile these shorter profiles are 300 mm, so I made it the same.
