Summary

found modeling error
15mm and 45mm platform are slightly undersize. v2 stl file fixes these platform diameters.

Modular display stand for 25mm round base figures.
Designed for small-screen resin printers. Slicer image shows stand and link on 6" diagonal size printer with room to spare. Photo shows three stands and two links laid out on 9" diagonal build plate.
Stands may be used independently, or link can be used to set spacing between adjacent stands. Any number of stands may be lined up on your shelf. Bond link to stands for better support and stability. Stands in staged photo are not bonded (or nested well)... you can do better.
Platforms are at 15, 30, 45, 60, 75, 90 and 105 mm elevation. Spacing may not be adequate for larger figures on adjacent platforms.
Let me know if you have suggestions or if this works for you.
