Hi,
I'm Tony Gray. I used to run rc-mini (m-chassis related) for well over 10 years and now I'm involved in FWD TC's.
Would you mind if I used your battery holder design as the basis for one of my own? I can refine and tidy up your basic design so it looks cooler and maybe also print better too.
I'm Senior Designer at Ford for Ranger/Everest so this sort of thing is what I do every day and I'd like to take what you've done and just make it look a little nicer.
With credit to you for the original design of course!
