This battery port cover is based off the charger port that comes with the Mavic.. It is to protect the leads from things touching them and starting a fire.
I made it because I will be flying on many airlines with my Mavic, and wanted the ports protected just in case, and I am sure others will be taking this drone everywhere too.
I printed this at .15 the first time, and .25 for the rest. Resolution doesn't seem to matter if you have good layer adhesion.
Printed in ABS but probably most materials will work. The hard materials may be best, as it fits tight, and requires some force to remove it.
print it with the closed end cap side on the bed.
