Quick Release Bosch Colt CNC Spindle Mount

A quick release mount allows attaching a Bosch Colt to 20x40mm extrusion rail, similar to Shapeoko or comparable systems, for versatile functionality and seamless conversion between milling and trim routing tasks. Also consider exploring http://www.thingiverse.com/thing:989778, featuring a laser adapter designed specifically to mount a JTech Photonics laser module or similar units onto the quick release mount I've created. The instructions below detail how I successfully manufactured this component using my Makerbot: Prints were made with PLA at low quality and 20% infill for the initial run. Due to deflection concerns, future prints may require higher infill levels. Clearing pin holes with drill bits facilitated precise alignment. Key design aspects include printing pins on their sides for added shear strength and counter-bores on mounting holes for enhanced stability, which might necessitate tweaking diameters according to your specific printer's shrinkage. To improve the clamping mechanism, I employed M5 washers around the screws due to initial over-deepening of bores. After experiencing issues with cams locking into place too tightly, I reinforced the design and tested with higher infill prints. Following usage spanning a year, failure of a holding tab prompted modification of critical components to prevent recurrence of similar problems. Revision 2 iterations incorporating enhanced stability features are available; note that STL files require updates.
