"Watt Geht Ab" Holder / Sandbox for the Worms

(German-only board game, so keeping it in German:)

In the children's board game “Watt Geht Ab”, the worms are stored in this sand tile at the beginning and after “washing away”. The problem is, when playing the game with small children, they constantly fall over there. This holder solves the problem. According to my girlfriend, this also works excellently in kindergarten.

I printed it in “Oak” PETG from Sunlu, but generally I find sand-like colors work very well. The choice of material itself is flexible here.
