3D Printed Speedo Drive

I caught this on the Facebook Norton Commando group. There is some good information there at times. It's harder to search for topics there. Plus I thought some folks on the forum would find this very interesting.

I've fitted a pair of superb new smiths electronics clocks from http://www.puca.co/productGL.html but I wanted to rid myself of the troublesome (for me, but I hear others find them OK) mechanical speedo drive so I 3D printed a lightweight magnet carrier and installed a small magnetic reed switch in the old housing.... here's some pictures of how I did it. It seems to work OK but I need to calibrate the speedo using the measured mile method as per the Smiths instructions. The main thing for me was to have a contactless system and say goodbye to those worn out gears, snapped drive teeth and broken cables that have plagued me on both my Commando and Bonneville.
If you are in the US I think Tom Kullen of http://www.smithsgaugesusa.com offers a service to swap the mechanical internals for an electronic version, but here in England I could only find mechanical based solutions.

He also posted the STL file in case someone wants to reproduce it.

I just picked up the new $200 printer from Monoprice. http://www.monoprice.com/product?p_id=1 ... 1&format=2

So far I haven't printed out any motorcycle parts... yet. I'm waiting to get some nylon filament that is much stronger that the PLA filament I have been using. PLA is easy to print and relatively inexpensive.

This light saber was 14 pieces and I learned a lot about printing while doing it. :mrgreen:

I do like this. 3D printing is evolving fast even printing stainless steel components. What next, heads, crank cases, pistons?

One cool thing you can do is print out the parts to be cast. Basically it's a filament that dissolves like lost wax.

Strange times we live in indeed.
