Simple Shuttle

thingiverse

Rediscover an aluminum profile at work and decided to create something with it. The customized design can be recreated by joining two U profiles at a suitable distance. Originally, the shuttle was made of heavy-duty steel; however, I preferred a lighter and adjustable alternative. The holes measure 6mm with a snug fit, except for the center top hole, which is 8mm to accommodate a rod from an old scanner. The assembly offers a millimeter's play in all directions while moving smoothly. A unique feature of this shuttle is the small elevations around the bearing bolt holes, which eliminate the need for washers. I plan to attach the belt driving the shuttle to the center bolts, ensuring it runs through the central channel. The top bearing mounts are blind holes to enhance print quality with comb turned on in skein-forge, although the results were limited. To use the shuttle, drill out the holes, install bearings, and move the shuttle back and forth.
