DIN Box (with internal rail), for power supply / transformator

This enclosure fits a (video) doorbell transformer that uses a DIN rail. Not always there is enough room left in a fuse box. This box/enclosure, has a 35mm DIN rail inside and has fits a double width DIN module. 

You can print it without supports, the overhang will print fine without. 

In this example you see a bell-transformer (8,16,24V) that nicely fits inside and clicks firmly to the ‘rail’ at the bottom. Two small holes at the top and bottom (the larger one goes at the bottom), will allow cables to run through.  In addition there is a half circle hole at the bottom that allows access to the “spring” that allows (de)attaching of the module. 
Two caps can be printed to prevent accidentially accessing the inside. 

Print in PLA/PETG or any other material (I printed in PLA and this is strong enough for me) @ 0.2 layer height.
