I have a Sony A6000 and also an older Sony Handicam (video) camera. Battery holder for the former are easy to find, but I have not been able to find a single one for NP-FV50 batteries, so I used the NP-FW50 holder (original I think: Sony NP-FW50 3-Battery Holder by rodskogj - Thingiverse) for inspiration and designed the holder for two NP-FV50 batteries in F360. Printed perfectly in PLA on my Mini @ 0.4 x 0.2 with 15% gyroid infill. No supports are needed.
The author remixed this model.
