Alternative Solderless Motor Mount for mostly printed cnc

Jan 20th Update
Added left and right angle files.
I have reduced the size of the holes for the 4x 3mm cable screws as I found mine were a bit loose.

Jan 10th Update
I have added a variation for mounting drag chain
The photo shows my prototype with single hole for mounting however I have since slotted the holes for various options .
If you are using my scad file you will need to have the original "Solderless Stepper Mount.stl" by Allted file saved in the same folder or it wont work.

I liked the solderless motor mount,

For mostly printed cnc machine by allted,

but decided to cap one end and open the other up a little.
I also wanted to put washers under the motor mount screws and found there was not enough clearance on the original.
