Recently I bought four level foil. Unfortunatelly I found no existing model on thingiverse and printables that allows the storage of those foils.
So I built this small container. I printed four of them. They are a little stackable, though I have not built it in a good manner.
For storing those container I used this box:
Parametric Box - no screws needed von rtm | Kostenloses STL-Modell herunterladen | Printables.com
with those parameters:
InnerBoxDepth: 80
InnerBoxWidth: 190
InnerBoxBottomHeight: 19
I think you should use 20 for InnerBoxBottomHeight. My box is a bit too small.
I printed “Levelfolie Einlage v2” three times and “Levelfolie Einlage v3 top” one time. The latter is the topmost container.
The author marked this model as their own original creation.
