Hypercube Evolution (NO brass inserts Version)8mm X-carriage

Making some changes to the X carriage so that 3mm nuts can be used instead of brass inserts. I found the inserts were a little close to the side wall and messed up my bearing alignment.

If the bearing were in stalled before the inserts then there will be no problem but i decided to make the change anyway.

7.15.2017 Revision 1 & 2. These semi tested
Rev1. removes brass inserts from the sides and allow M3 lock nuts.
Rev2. removed all brass inserts. The remaining holes use regular M3 nuts, not lock nuts
Added radius to the edge to make the bearing a little easier to insert.

I have printed Rev.2 and tested 1 side with screws and nuts and it seems to work.
A few tweaks I want to make are making screw slots radius'd instead of square to add a little strength in the area the nut pulls on. Its probably fine as is but ill make the change a
