These painter’s props (also called painter’s pyramids) let you elevate your workpiece while painting, staining, or finishing.

The small pointed tips minimise surface contact, allowing you to work on both sides without sticking or marking. They print fast, stack neatly, and make great consumables from end-of-roll filament.
 

Also included is the French Cleat mount.
