Grumpy Tree Mount 20mm STL

3D Printed mounting system for the Gilbert Engineering Grumpy Tree. The mounts provide a frame structure behind the coro to increase strength and allow mounting to various surfaces as well as provide rigidity to the prop after it has been slit in half for shipping. The mounts are sized to fit 20mm conduit conduit and are designed to be zip tied to the coro. In order to construct the center horizontal conduit brace, two 25mm PVC T fittings can be inserted along the vertical sections of conduit using the included bushings file that allow the conduit to fit inside of the PVC. For ground installations rebar can be driven into the ground and the conduit can slide over the rebar to hold the prop in place. At a minimum the rebar should go into the ground at least 18″ and extend into the prop 18″. Guy wires or additional EMT structure like the one illustrated is highly recommended for those that experience winds.
