SCX10 Pro transmission front dig conversion

I designed this part to convert the Axial scx10 pro transmission from selectable rear underdrive, to selectable front dig. This replaces either set of gears in the rear of the transmission (standard or underdrive) to disengage and lock the rear output on the transmission when selected. The rear axle will be locked, and the front axle will still drive to allow for tight turning when crawling.

You can either have standard drive and front dig, or underdrive rear and front dig depending on where you install it.

I'm running the standard design in my crawler. After sending my order to the printer (to be done in stainless), i streamlined the design a bit for metal prints to save some weight. The standard version (in stainless) weighs ~6 grams more than the underdrive gear set it replaced in my car. The updated design should be the equal or less than the stock gear weight, and still function the same.
