Makita Mega Battery for 18650 (BMS version - BL1830)

This is a remix (draft) of the "Makita Mega Battery for 18650 10x extended 15x 20x replica" (https://www.thingiverse.com/thing:5026796) with the following changes:

• modified version of 1.stl + 2.stl to fit a BMS (BL1830) like https://aliexpress.com/item/1005003988193884.html
  • added standoffs for the pcb screw positions
  • hadn't proper flat screws available, so I used a 3d printing pen to fixate the pcb
  • wiring is complicated if you use thick cables, due to small horizontal space between pcb and battery pack (maybe the 2.stl should be increased in height to make room for cable management)
• repaired version of 3.stl to work with Slic3r
