GE Mini Tree Mounting System 20mm 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 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. This metric version is designed for 20mm conduit. The 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 rebar into the ground and slide the conduit center of the mini tree over the rebar. Please select the version of mini tree you have and the size. The Rev 2 mini trees were released in March 2021 and the size differences in the trees makes the original and Rev 2 series of mounts incompatible with each other.

The sizing of the trees has changed slightly from the original version to the Rev 2 version. The heights of the trees for the various sizes are as follows.

  • Original Version – Mini 22″, Small 32″, Medium 37″, Large 48″
  • Revision 2 – Mini 23″, Small 33″, Medium 36″, Large 43″

Parts List:

  • 20mm Conduit  Link to Conduit
  • (8x) M4 x 12mm machine screw or similar sheet metal screws for securing EMT to bottom mounts
  • M4 or similar x 12mm sheet metal screw for use with the alignment jig
  • (5x) M4 or similar x 12mm sheet metal screws for securing the top mount (10 screws are needed on the large)
  • M4 x 50mm machine screw for locking conduit in place on top mount
  • (2x) M4 x 25mm machine screws for the star
  • (2x) M4 nylon lock nuts for the star
  • M6 x 12mm machine screw for the star
  • Zip Ties

Recommended lengths for cutting EMT conduit: (My personal preference on the vertical section is to extend the EMT 15.2 cm beyond the top hub)

Original Mini Trees

  • Mini Size: Vertical EMT 71 – 76 cm, Horizontal EMT (4x) 162 mm
  • Small Size: Vertical EMT 94 – 99 cm, Horizontal EMT (4x) 225 mm
  • Medium Size: Vertical EMT 109 – 114 cm, Horizontal EMT (4x) 254 mm
  • Large Size : Vertical EMT 135 – 140 cm, Horizontal EMT (4x) 330 mm

Rev 2 Mini Trees

  • Mini Size: Vertical EMT 72 – 77 cm, Horizontal EMT (4x) 167 mm
  • Small Size: Vertical EMT 94 – 99 cm, Horizontal EMT (4x) 238 mm
  • Medium Size: Vertical EMT 105.5 – 110.5 cm, Horizontal EMT (4x) 270 mm
  • Large Size: Vertical EMT 120.5 – 124.5 cm, Horizontal EMT (4x) 324 mm

Note: Due to the smaller top diameter of the 23″ mini size on the Rev 2 tree, the opening on the top hub for the pigtail passthrough to the star could not be made the same size as the other versions. In order to pass the pigtail end with the cap through the hub, you will need to use a heat gun to soften the cap so it will slide off and reattach it when on the other side.
