Designed this modular stands to organize my paints. I'm sharing as it might be useful for others.

I made available several modules holding as follows:

• Module_16.STL -->16 jars
• Module_20.STL -->20 jars
• Module_28.STL -->28 jars
• Module_35.STL -->35 jars

I made also available the top holder that should be glued and allows to hold jars of different hights:

Module 16:

• Module_16_Tops_A.STL, 2 per module.
• Module_16_Tops_B.STL, 1 per module.

Module 20:

• Module_20_Tops_A.STL, 2 per module.
• Module_20_Tops_B.STL, 1 per module.

Module 28/35:

• Module_28_Tops_A.STL, 2 per module.
• Module_28_Tops_B.STL, 1 per module. (2 per module for 35)

In the slicer, for better finish rotate the tops 90 deg (X axis) when printed glue the upper sideprint.

Hope you find it useful.
