Ridgid 18V Battery Mount - goldilocks version.
I tried all the Ridgid 18v battery mounts, and found that I liked the one from FLA_Labs the best, but wanted a bit more versatility in mounting options, as well as some more efficiency in regards to print time & filament usage. So I remixed this as sort of the goldilocks Ridgid 18v battery mount... It uses a lot less filament than the original, but isn't quite as minimalist as the smallest options out there, so still has maximum stability. Batteries slide easily in and out, and even my big 8ah battery feels 100% secure in there. (Which wasn't the case with the smaller mounts that I tested!)
This version removes all the interior bulk, which was unnecessary to hold the battery, but retains the full size side supports and fitted top. It adds recessed mounting holes, for a total of 6, so you can really mount it however you want. So it's quicker to print, and still maximum sturdy.
I've printed it in both PLA and PETG, and standing prints need no supports.
