This is a high visibility door mod for the Armadillo SCX10 Off-road truck 3d printed body. Found from here: https://makerworld.com/en/models/556645#profileId-475535
It offers an alternative look to the default door.
It uses the same door handles as the default door so that can be re-used. One 4x2mm round magnet is needed per door and 2 extra M2x4 screws per door compared to the original door. The model contains additional print supports that can be cut-off after printing.
The author marked this model as their own original creation.
