First attempt at using FreeCAD to edit/combine parts found online, so it's not the prettiest thing ever. Sorry.
This piece changes the orientation of the Jsaux Mod Case Strap Attachment from horizontal to vertical. Needed this because all of my battery banks are too long and all my USB-C cables too short, leading to either:
A) The cable being strained
B) My right trigger being partially blocked
C) The back buttons on the right of my Deck being blocked.
This takes the Central Mount from Sp4m's Modcase Mount Design Environment, slices off the ends, and attaches it perpendicularly to the back of Wild_Coyote97's Universal Mount
Now, my battery is aligned vertically and the cable is out of the way.
Should print in 25-40 minutes depending on layer height. Supports may need some help (I used the filament cutter that came with my printer to pry on side off). Current one I'm using was printed at .32mm and seems to hold up nicely.
I found that the Male connector (which goes into to the original JSAUX puck) has a tendency to get stuck or not attach snuggly/loose enough to remove. I recommend GENTLY heating this side of the print with a hair dryer or heat gun for a few seconds, then trying to attach/detach it from the JSAUX puck. After that it seems to work just fine. I also went over the Female end with a file just to get it ever so slightly loose. Be conservative with both of these steps, you can always heat it up more or file more away.
If the print gets stuck to the original Puck, you can just heat the whole thing up and they should slide apart (though be warned, this may damage both of them).
The author remixed this model.
