A simple thing to solve a small problem.
The condiment bottles in my fridge always fell over, with the rounded bottom and the grid shelf. So i designed pot-like coasters with grooves in the bottom that fit the grid of my fridge shelf. The important parameters, grid and bottle size, can be changed in the customizer, or, if it doesn’t work, in OpenSCAD.
Print settings are not really important.
This is just a few cylinders, no fancy rounding or the like.
There is some design history available at my github repo.
In the end i had to take out a bunch of non-ASCII characters to make the customizer work, but now it seems to do it.
