Hộp hình nấm (Mushroom box)

A mushroom-shaped box and its FreeCad (v1.1.1) file so you can easily change its size.

NOTE : the FreeCad spreadsheet is in french (sorry :-). The two values you may change are

• the foot diameter (in cyan), which is the main driving parameter (all other measurments depend, directly or indirectly, from this one).

• the foot height (in green), currently depending on the foot diameter but can be changed at your leisure.

Since my FreeCad-fu is not that great, if you want to change the foot diameter, I strongly advise to go by 20/40 mm increments. The model should not break, whereas it may loose its mind if you go from the current value (50 mm) to something quite bigger. The recompute time for small increments is negligible compared to trying to repair a model gone mad.
