About this 3D model
Mould King 10015 - Motorized Santa SleighModified Technics 1x4 Brickby RebelTaz In the instruction manual, on steps 65 and 101, there is a Technics 1x4 brick. If you install this as directed, the worm gears in steps 66 and 118 hit the middle two pins on top of the Technics brick, binding the gears if you try to force it to fit. To remedy that, I have created this special brick with those two pins missing. Printed on a resin printer, the tolerances are a perfect snug fit with just enough play for the axle to ride smoothly. Other than this, this is a wonderful model and well worth the price.
