Tamiya Sand Scorcher mechanism box (6 cell battery)

Replacement mechanism box for the Tamiya Sand Scorcher Buggy that enables a 6-cell battery to be used.
Two versions are here, one is a 5-part assembly, if your printer is big enough. The other is an 8-part assembly for those with smaller printers. Both versions use parts 1 and 2, then for the 5 and 8 part assemblies print the parts named 5-x and 8-x respectively.
Some support is necessary, but it has been kept to a minimum.
I superglue the parts together for the initial assembly, then go over all joints with a 2-part structural adhesive for a long lasting part.
STEP files are included if you need to modify.
