XLS450 Snowflake Mount 20mm STL


These are the STL files for 3D printing the mounting system for the Gilbert Engineering XLS450 Snowflakes. 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 and are designed to be zip tied to the coro. A screw can be inserted through the top of the mount and into the conduit to secure it in place. The XLS450 mounts are available in two configuration versions, Cross Mount and Mega Mount. The Cross Mount version utilizes a 25mm PVC cross at the center junction which you can then fit with conduit to PVC  bushings which are printed using the included bushings file. This allows the smaller 20mm conduit to fit securely inside of the PVC fitting. The Mega Mount version utilizes a 6 spoke printed hub at the center junction to connect the conduit arms with one of arms being able to pass continuously through the hub.

Important alignment information: The design of the XLS Snowflake is not symmetrical about its axis. Variations in pixel hole locations exist between 2-4 millimeters if the prop is mirrored horizontally or vertically. If the mounts were designed to fit perfectly with this asymmetry, then each mount would be a unique design and any rotation, horizontal or vertical flip from that one orientation would cause the mounts to fit quite poorly. This obviously would be problematic, so the mounts have been designed to fit in the median location and the pixel openings are large enough to account for the asymmetry. Our recommendation for fitting the mounts to the XLS Snowflake is to first place the XLS on a flat surface before pushing pixels and then place the mounts on the prop with the conduit per the renderings. With the mounts inserted into the conduit, you can then adjust the placement to achieve the best overall fit and mark the coro for making the zip tie holes. Once the holes are made, attach the mounts to the prop with zip ties, but don’t fully tighten them down until all the conduit sections are inserted so there is some wiggle room for making adjustments to the mounts.
