Description

I made a DIY version of a V-Mount-Back for the Sony A7 IV similar to the Cineback.

The model is based on the Smallrig cage 3667b. This cage also supports Sony A7s III, A7r V, A7r IV and A1, but i did not test my model with those cameras.

The printing procedure is pretty straight forward, i only added supports. The infill and most other parameters can be adjusted (i printed 20% infill personally) as long as they don not vary the wall thickness. Otherwise pressure fit parts wont fit or be to lose. That is also why i advise to print with 0.12 mm layer height, because i made measurements and tests to this thickness.

But feel free to experiment and optimize:)

There are also two versions of the door, one with cable hole, the other fully closed. Only one needs to be printed, whichever you like best.

All the parts (with links) and assembly is in a PDF as a documentation. I really tried to make it understandable and easy to build yourself;)

Have fun and keep filming:)
