He is very specific about the movement of the wheels and all previous designs ‘failed’ his tests. This design is the best I found, and he has approved it. So, have a go!</p> <p>You can opt to slice the train for various colour printing which works well. (I have included a GCODE sliced file for the Original Prusa Mini).</p> <p>I would recommend printing sections of the train in different colours for it to stand out. Either slice it in different parts of prepare it for multiple colour printing.</p> <p>Insert the magnets into the slots: make sure you have two different polarities on the locomotive! Simply reverse one.</p> <p>Add a dab of superglue on one of the axel parts before assembling.</p> <p>Sources for parts:</p> <p>• Magnets: <a href="https://www.amazon.co.uk/gp/product/B007UOXRY0/">https://www.amazon.co.uk/gp/product/B007UOXRY0/</a><br/> • eBay search for: 10x3mm-Rare-Earth-DIY-Strong-Ring-Neodymium-Disc-Round-Magnet-Hole<br/> • Upholstery tacks: <a href="https://www.amazon.co.uk/gp/product/B01MYSZWM6/">https://www.amazon.co.uk/gp/product/B01MYSZWM6/</a><br/> • eBay search for: UPHOLSTERY NAILS / STUDS / TACKS / PINS - CHROME SILVER NICKEL FREE P&amp;P</p> <p>Update: printed three rainbow versions for the grandchildren to celebrate the NHS</p>
