Engineer Designs Custom 12mm Spring Assembly Using Adjustable Tension This spring setup features precision components suitable for applications in MK7 and MK8 configurations. Gear sets include a selection of 11mm gear systems. Key bearings comprise the high-quality 624, 608, and 604 types, which ensure reliable motion across mechanical devices. Powerful nema17 motors serve as primary movers, allowing precision control over linear movement patterns. Key Components A specific spring tension requirement is met through careful placement of precise spring segments in this custom design: - A combination of three identical pairs (each with different lengths) comprising a pair with a 3mm diameter by 10mm length spring (X2) - A solitary, non-paired component measuring 15mm by 3mm (one time) Mounting for the aforementioned assembly features high-performance 624 bearing systems. Customizable options enable integration of precision-matched motors into a singular unit that also accommodates distinct configurations through variable adjustments using tension adjustment dials: Standard accessory elements Tension dial: four-prong, with individual pin diameter size measured at 15mm.
