I have this set: https://www.amazon.com.au/Alcohol-Bottles-Concentrated-Alcohol-Based-Painting/dp/B09CYZL21Y/ref=pd_lpo_2?pd_rd_i=B09CYZL21Y&psc=1 of alcohol ink pigments to add to resin.
I wanted a neat holder for them that also looks nice while stored on the shelf.
I wanted to be able to see the color of the ink in the bottle too, so I made the holster for the bottles at 60 degrees to allow the liquid to be more visible from side-on
I made some holes you can either use, or not, for 4mm diameter 2mm tall magnets to be inserted into the help with the stacking, 1 thick on the bottom, and 2 on the top.
This should be printed without supports, I printed mine at 20% infill in PETG, but I recommend having at least 3 perimeter layers to allow good wall thickness on the thin sections around the edges of the bottle slots
The .f3d file is a mess with several alternative ideas in it, feel free to mess around with it and remix, I'd love to see other people's takes :)
