LINEAR RAIL WITH STEPPERS

Açıklama

Linear Rail for NEMA17 SteppersA compact, fully printable linear rail system designed for NEMA17 stepper motors. This project utilizes common, accessible hardware to create smooth, reliable linear motion. By including printable GT2 pulleys, this build is perfect for makers who want to minimize their BOM while maintaining performance in small automation projects, camera sliders, or custom CNC builds.FeaturesAccessible Parts: Uses standard 608 skate bearings, NEMA 17 stepper motors, and GT2 belts.Fully Printable: Includes custom-designed printable GT2 pulleys for a complete DIY experience.Simple Tensioning: Innovative belt tensioning system—simply wrap the belt back on itself and secure with a zip tie.Easy Printing: Designed to be printed in PLA with no supports required.Compact Design: Minimal footprint while maintaining structural rigidity.Versatile: Uses standard M3 hardware throughout.Hardware Bill of Materials (BOM)(1x) NEMA 17 Stepper Motor(4x) 608 Skate Bearings(1x) GT2 Timing Belt (Open Loop)M3 Screws (various lengths): Recommended: Assortment of 8mm, 12mm, and 20mm M3 screws to cover assembly requirements.Misc: Zip ties (for belt tensioning).Printing RecommendationsAll parts were designed for easy FDM printing.Material: PLA (PETG or ABS also work, but check tolerances for shrinkage).Supports: None needed!Infill: 20-40% (suggested Gyroid or Cubic for structural strength).Perimeters: 3+ walls recommended for rigidity.Bed Utilization: For maximum length on a 220mm x…
