<p>Linax created this awesome model that I simply had to make.<br/> Thank you Linax<br/> I did find a couple of small changes that I wanted to make;<br/> The bearing now has a shoulder to hold it in place, the internal square hole is 0.2mm smaller, again to hold it tighter on the shaft, it is also 2.5mm longer to hold the large cog more stable.<br/> I have also included the original sized bearing with the shoulder for the hand crank side.<br/> The other modification I wanted was to thicken the oval spacer by 1mm, again to constrain the gear and cams.<br/> There is a video at <a href="https://youtu.be/SVGj1WbhWPs">https://youtu.be/SVGj1WbhWPs</a><br/> I hope this is helpful, please let me know your thoughts/opinions</p> <h3>Print instructions</h3><h3>Licence: Creative Commons - Attribution - Non-Commercial - Share Alike Category: Mechanical Toys Print Settings</h3> <p><strong>Printer Brand:</strong> RepRap</p> <p><strong>Printer:</strong> Original Prusa i3 MK2</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.3</p> <p><strong>Infill:</strong> 20%</p> <p><strong>Notes:</strong></p> <p>Printed in PLA @ 70mm/s</p>
