5/8 and 13/16 Spark Plug socket holder (3/8in drive) for the Gridfinity system. This is a 2x1 Gridfinity container. Printed with a 0.6mm nozzle, use Cura Post-Processing for a filament change at layer 70 and again at layer 73. The sockets I used to make this were Husky spark plug sockets, but these should work for other brands with the same size and drive. This is part of a massive mechanic's roll cart collection I'm putting together. I will be posting more models here soon and will eventually be posting a master collection containing everything.
