Lionel Polar Express Air Kit

thingiverse

Want to spread holiday cheer in the office? This set of adapters lets you hang the Lionel Polar Express from grid panel type ceilings, giving it a unique look. It comes with clip-on brackets for track junctions and anchors that fit perfectly into ceiling grid corners. Find a 4 by 4 panel section where core panels aren't blocked by a light fixture so adapter clips can be inserted easily. Add some light plastic or metal chains between brackets and anchors, and you'll have a secure way to mount the track to the ceiling. I'll post pictures of my final install later on, including a parts list. To create a circle, you'll need 12 sets of clip and anchor pairs. Enjoy your Lionel Polar Express display! Print Settings: 30% infill PLA 1.2 mm shell layer I installed the Lionel Polar Express using a 3 by 3 panel section for stability. The longest connections require additional cross-connections to nearby ceiling anchors. Choosing the right chain size determines the increments available to optimize load balance and tension. Be prepared for some play in the track, which might cause passenger cars to detach during runs. I'm adding a special clip to prevent uncoupling from happening.
