Support your workpiece off your workbench whilst painting.

I've included two versions,

1. A pyramid which has two flanges with screw holes to optionally secure the pyramid to your workbench along with a slot which allows multiple pyramids to nest.
2. A plain pyramid without flanges or slot.

Each pyramid is 45mm tall and each side of the base is 59mm. The flanges protrude by 15mm.

The peak is rounded to minimise marking to the underside of the workpiece.

These come off the printer with no supports, just check the top has printed cleanly and there's no sharp point, if there is it only takes a light sanding to fix.

Printed on an Anycubic Kobra X using default settings for PLA. I'm sure PETG would give better strength, but I only had PLA. I've been using these for a couple of weeks now with no problems.
