3-D printed parts for Model B ergo

[AndyGadget]

A while ago I uploaded a design for a lever to allow easy adjustment of drag factor from the seat and I've now added a 1 to 10 scale to accompany it.
The scale is designed to attach to a drag factor reducing 'speed ring'.

For the uninitiated, the .STL files on Thingiverse are the files which contain the printing information. These tell the printer's extruder where to move, how fast and when to extrude plastic. The 3D printer lays down layer after layer (typically 0.2mm high) to build up the final shape of the object. If you don't have access to a 3D printer, there are now many companies who will print off parts for you from an STL file.

As the Concept designed speed ring is no longer available (in the UK - may be in the US) I built my own out of 3mm MDF. This allows drag factor to be varied from 95 to 220. If there's interest I'll reverse engineer (i.e take it off and draw around) mine and post plans here.
