Din rail fixtures

This is a little din-rail (35x7.5 mm) fixtures kit which one can use as separate tools or as parts of custom electronic cases.
- First part is only fixture-form aimed to be added to any case model.
- Second part is threaded fixture which suppose to have two M3 nuts inserted in slots and use screws to fasten flat parts or case buttoms.
- Third part is short fixture with two-position latch which allows fast and simple fixation. This part supposed to be glued or screwed on case`s bottoms (even several fixtures per case).
- Fourth part is enlarged version of previous for using with bigger cases.

All parts are supposed to produce via 3D-printing, viscous materials are recommended. Switch fixtures base have two-part construction for better print conditions, assembld with glue.

P.S. One should be careful about latch height when print latched fixtures. 3D models have no vertical gap between base and latch to prevent fixture backlash. In ordinary case it is recommended to grind latch part to make allow its free moving in fixture (or decrease its height before printing if you can reach sufficient parts quality this way).
