Mounting plate, fully customizable, update

A customizable mounting plate or spacer*. Originally designed for 2020-frame, but also usable for other purposes.

Update may 2019: customizer more user-friendly

Customizable in "Thingiverse Customizer". Don't be disappointed at the start, it is the basic shape, a small plate with a hole. The Thingiverse Customizer is buggy (may 2019), use the Openscad- customizer instead if it don't work. Openscad is a free and opensource program (http://www.openscad.org).

The left and the right plate
You can add a mounting-plate at the right and left of the base. Keep in mind that the plates are measured from the baseline (the middle) . If yo use it on a 2020-frame, add 10 mm to the widths of the plates.

The holes
You can add up to ten holes in your design**.
Off course you need holes to mount the mounting plate to the object (printer or ??). Put those on the baseline (x=0, Y>0).
The Y-coordinate is always positive and is going from top to bottom.
The X-coordinates can be negative
