I got a hana modz dna 30 clone from my local B&M and immediately wished it was easer to remove the battery door. Problem solved!

I took a bit of inspiration from this video:

I happened to have these magnets laying around and they work perfectly. Very strong!

If you try this, make sure the plastic window (it's red in my mod) is secured with superglue to the body of the mod. The top of mine was already quite secure, a little dab of glue on the bottom, held for drying with a small woodworking clamp, did the trick.
I haven't yet done anything to the screws to make it look nicer. Cutting off the screw heads and gluing them in place on the door would probably be the easiest solution.
