This is a parametric organizer for generic spice jars from Amazon. These are my specific ones. They're about 46mm (a bit over 4.75") square(ish).
The attached model is trimmed down about as close and flimsy as I could make it as the fit in my drawer was very specific. If this is going to be used on a shelf or something I would probably make the walls a little more robust.
Onshape Model if you want to remix, regenerate, whatever
If desired I can probably generate some additional variations and attach them here but it's also easy to do in Onshape by changing the relevant variables.
The author marked this model as their own original creation.
