I3 rework CNC router

thingiverse

This adapter mounts a PCB router to an I3 rework carriage. To print it successfully, orient the model vertically with support material, ensuring the carriage mount is upright and the motor holder is horizontal. Using 60% infill will yield the strongest print. When using Slic3R, the software defaults to the correct orientation. I sourced my motor from Aliexpress at http://www.aliexpress.com/item/2015-NEW-Mini-Micro-Electric-PCB-Motor-Drill-Press-Drilling-bits-Tool-Twist-Drill-12V/32580675006.html; its O.D. is 29mm. A small bracket attaches to the side, keeping wires from ripping off the motor. Rotate this part 180 degrees so that recessed screw holes face upwards for better printing results. I used M3x12 plastic screws from McMaster at http://www.mcmaster.com/#96817A370. These were already on hand but proved a tad too long; one screw touches the motor before tightening the clamp, so either change sources or purchase shorter fasteners for the holes - 10mm might suffice.
