Installing USB Charging into Limited Edition Joycon Grip. Mario Switch Controller Upgrade.

I give a brief overview on transplanting the inner gubbins of a normal official Nintendo charging grip into their limited edition Mario Blue grip. This means I can now use all the official Mario merchandise, alongside upgrading from the plain black controller they only seem to sell with the built-in chargers. I have now made my limited edition joycon even more limited!
Fairly easy process, 4 screws to remove on back holding down top cover, 3 screws holding down electronics, 3 screws holding down each of the rails on the side. Unscrew all this, then move electronics and rails to replacement controller. Then with a dremel, perhaps you can get away with a soldering iron you don't mind trashing, carve a hole for the location of the USB charging port and a hole for the charging light to poke through in the top cover. Put back together, installing the 4 case screws again. Joycons should now charge fine when slotted in and connected to a power supply with enough power.
I do not accept any responsibility if you damage your equipment by following these instructions.
