Motor to lego technic adapter
thingiverse
Update - 19th Sept - Turned this into a customizer. A converter to link a small DC motor (found in many toys or easily purchased) with a Lego Technic 'x' having a shaft of 2mm diameter. I've discovered that a 2.2mm hole makes for a good tight fit, but different printers and materials may vary, so the scad file is available for you to experiment with. It should also be simple to adjust the length of the shaft if needed. Printing in PLA at 100% fill has given me consistent results every time. Print Settings Printer: Balco Rafts: No Supports: No Resolution: 0.1 Infill: 100%
