Gridfinity 2x3 Paint Organizer - Combo Holes

This design was inspired off Shorco's Paint Organizer for 22ml sample paints. New model is expanded to accommodate multiple sizes by adding stepped down holes. 

Paint tubes designed for this holder: 

1. Liquitex 4 floz (118ml) Acrylic Paint. Lid diameter is ~38mm 
2. Liquitex 2.4 floz (75ml) Acrylic Paint. Lid diameter is ~38mm
3. Liquitex 2 floz (59ml) Heavy Body Acrylic Paint. Lid diameter is ~29mm
4. Liquitex (or generic) 22ml Sample Paint Tube. Lid diameter is ~24mm 

The holder is built on the gridfinity system. If you are interested in the pegboard shelf shown in the cover photo, I have that model uploaded as well: Pegboard Straight Hook Gridfinity Shelf by BigJohnson | Download free STL model | Printables.com

Models included are both a lattice wall so it is easier to see through the wall and see labels. Alternatively, solid walls if you want something a bit stronger. Both versions have magnet or no-magnet models. 

I printed this in Polymaker CF-PLA. Layer height was 0.2mm (on speed mode) for my Prusa MK4S. Infill was set at 5% and it works fine - I suggest 10%-15% to ensure it holds up to time. 

Note - I did not use supports on the print despite there being very long bridges at the arches of the grid inserts. It caused no issues for me, but you could also make sure the bridge just runs at 45deg angles and it would solve any issues. 

I expanded the grid size to 2x3, added multiple options for walls (lattice or solid), and modified the paint holder holes to accommodate multiple sized paint tubes (22ml, 59ml, 75ml, 119ml).
