Anycubic i3 Mega Bottom Panel Spacers

I wanted better airflow, but clayrev's thing would have taken way too much time to print.
So, I hacked this together.
These spacers will separate the stock bottom plate from the printer's body by 14 millimeters, enough to clear the gantry's lower bar.
You'll need to print 8 spacers, total. Two should be the plain octagon version: these go on the side screws nearest to the gantry bar. The other 6 can be either type, but I recommend `_wide`. It's easier to hold onto while you install the screw.

UPDATE: I added/updated the SCAD file, it should be customizer-friendly.
