GE Mini Tree Mounting System STL


3D Printed mounting system for the Gilbert Engineering series of mini trees. This mounting system utilizes a lower and upper center hub and 4 lower outside mounts (5 on the 19″ rev2 small size) that attach with zip ties to the mini tree. The included star mount is designed to fit the Star 12 single or double layer star. 1/2″ EMT conduit is used to join all the printed parts to create an internal skeleton that securely supports the mini tree. To install the tree, simply insert 1/2″ rebar into the ground and slide the EMT center of the mini tree over the rebar. Please select the version of mini tree you have and the size.

Discount will be reflected in cart. Important Note: The Rev2 mini trees were released around March 2021 and the size differences in the trees makes the original and Rev 2 series of mounts incompatible with each other. Furthermore on the Rev2 trees the small size changed from a 33″ tall tree to a 19″ tall tree around October / November 2021. In 2023 GE dropped the name Rev2 from the description on their website, but the mini trees are still the Rev2 design. If you have any question as to which version you have or what you need to order, please contact us prior to ordering.

Recommended lengths for cutting EMT conduit: (My personal preference on the vertical section is to extend the EMT 6″ beyond the top of the tree)
