Raspberry Pi + GSM-Modules Case

This Case is designed to fit a Raspberry Pi 4 and up to 6 GSM (SIM800L) modules. It also fits a RTC-Module and a LM2596 buck converter (to Power the GSM-Modules wit 4.2 Volts).

In addition i designed brackets to optionally add an 7" Raspberry Pi touch screen.

The mount for the fan should work with all 40 mm fans, the Noctua fan i used sitts pretty tight. 

For better cable management, i added some loops on the botton that can be used for cable ties.

For printer settings i suggest a maximum layer height of 0.2 mm and to use organic/tree support.

Screws needed: M3x20 for the case assmbly and to mount th optional display, M2.5x6 to mount the electronics. The GSM modules are press fit into the slots.
