Lionel Polar Express Air Kit

thingiverse

Want to spread holiday cheers in the office? This set of adapters allows you to hang the Lionel Polar Express suspended from grid panel type ceilings. It provides clip-on brackets for the track junctions and respective anchors for the ceiling grid corners. Find a 4 by 4 panel section where the core panels are not blocked by a light fixture so the adapter clips can be inserted. Add some light plastic or metal chains between bracket and anchors and you can mount the track securely to the ceiling. I will post pictures of my final install later on including a parts list. You will need 12 sets of clips and anchor pairs for a circle. Enjoy! Print: 30% infill PLA 1.2 mm shell layer I did an install using a 3 by 3 panel section which is best for stability. The longest connections need additional cross connections to closer ceiling anchors. The choice of chain (size of chain links) will determine the increments available to optimize load balance and tension. There is a chance to lose a passenger car during runs due to more play of the track. I will add a special clip to prevent uncoupling from happening.
