Has a tall chamber in the back for items like combs, razors, etc. The front two tray-like chambers are for small items. The rounded area on the right-hand side is for a small electric razor.
The back chamber is tall enough that items put there will fall over without the dividers. Print the dividers STL and connect them together so the three narrow dividers are slide into the slots on the wide one. The connected dividers will drop into the tall chamber and provide support for items added there.
