Sequential Simracing Shifter

thingiverse

WORK IN PROGRESS!!! Sidesprings are redesigned as a thin component, requiring an additional part to serve as a leaf spring. Each side needs a thickness of 3mm, and I'm currently using three strips of 1mm thick carbon fiber on each side. This is my approach to a sequential simracing shifter, still experimental due to some problems and varied designs of the "Spring side.stl". The current design and material selection seem to be working effectively. The goal is to achieve more gear shifting feel than other printable designs I've encountered. The design employs "Sidesprings" to provide an initial resistance to the shifting motion. On my unit, everything except "Spring side.stl" and "Shaft inserts.stl" has been printed in PLA. The "Spring side.stl" and "Shaft inserts.stl" are printed in PETG to prevent them from snapping after a while. To achieve a smooth profile and springy strength, "Spring side.stl" needs to be printed standing on the side with concentric layers and 100% concentric infill. Similarly, "Shaft inserts.stl" should also be printed in this manner. My unit is connected to a Leo Bodnar BBI-32 Button box board. Hardware required: 6 M5 nuts 4 M5x40 countersunk head screws 2 M5x18 countersunk head screws 2 M8 nuts 1 M8x80 threaded rod 2 12.9x5.9 micro switches with R-shaped lever The "Housing middle.stl" and "Housing right.stl" contain 5mm countersunk holes for mounting the shifter to something.
