1/32 Scale Slot Car Timing Gantry
thingiverse
Human: Engineered for 3-lane slot car tracks, 3 1/2" lane spacing, and 3mm infrared LEDs. Clearance is exactly 94mm from the track surface (assuming a perfectly flat track) to the bottom of the LED (which protrudes 2mm below the gantry overpass), utilizing standard 3mm infrared LEDs. Width is approximately 348mm for version 3, but slightly increases to 358mm for versions 4.0 and 4.1 between the uprights. The top was printed in two separate pieces due to its large size. Simply join these two top pieces together with the uprights using PLA solvent or medium CA glue - whichever your preferred method happens to be. Version 4.0 boasts extended span of 10mm as well as two added corner braces for enhanced stability. Version 4.1 takes it a step further by extending the span by an additional 10mm and incorporating built-in corner braces for maximum support.
