An update on my completed battery replacement case...
There are a couple of tweaks left to do on the design but t is pretty much there now and as i only have one functional battery (one more than i started with
) i probably won't do much more on this.
I did some more work on the design and button / LED positioning along with extra bits to get a neater fit.
Once printed i fixed the original switch and led strip using a 3D printing pen using the same PLA used for the print.
Then popped the rubber cover back on the LED strip
Fitted the circuit board to the posts, again using the 3D pen.
Added a couple of layers of double sided foam strip to secure the battery to the curcut board - very strong stuff used!
So thatgave me a battery back together with a balance lead available.
Fitted nicely and powers up as per the original case.
I used a velcro strap to retain in position to test it.
Flew fine without any issues.
I was concerned that the velocro could move, possibly touching the power switch or covering a sensor or camera underneath so i designed this retainer.
Added bobbles to the sides of the battery case so that it cannot move laterally to touch the power button and of course now no where near the sensors or camera underneath. Fits easily and gives a nice firm fix so that the battery can't go anywhere now - job done and designs updated so that everything is built in. Also kept the balance lead short so that it cannot get near the props.
So there it is - a DIY Mavic battery case that has got me flying again.
If interested i will post the stl files on here or Thingyverse.
