Sho(r)t Timer Housing

To continue my blue/green espresso accessories series, i decided to make a timer for my coffee grinder.
When i made some pcb in the past and needed a housing, i had to buy some cube looking housing in the electronics shop. Drilling and file some holes in and accepting the makeshift look of the result.

Now we have the 3D Printers and i have after apox. 30 years of electronics tinker the tool to create my own (first) housing.
The housing is made for an 5x10 cm pcb and has inlets for the wires. Also it's supplied with screw columns which side effect is to stabilize the housings walls.
The lid carries the main switch, the potentiometer and the push button. Also i made some frames around the switches which can be illuminate by 5mm LED from the bottom.

I will not describe here the electronics an wiring. But you can find millions of NE555 circuits for timing applications in the www.
Also the holes may not fit to the switches you have laying around, but the project may an inspiration for your needs and the source files are attached.
