3D Scan Marker Pyramid

i've seen different marker dot pyramids in video's and wanted to have a go at it and print my own. Came accross a design of Peel 3D, and made a slight variant of it.
Mine is more stackable.

I'm planning some variations where you can add magnets of velcro on the bottom.

credits for the design go to peel 3D
