Hello Robin
I assumed you printed the entire kit. My mistake.
That's what is really needed IMHO. Complete assemblies, printed on a 3D printer. De-skill the entire effort and turn it into a "press the button" manufacture.
So I gather then that you 3D printed the small bits. Printed the scale and attached it to Wolfgang supplied drums? It does look rather nice!

Brad,
I am certainly willing to make the 3D printed parts available to interested Navlisters as on demand sales or by other means but the a couple of things need to be borne in mind
- The pieces are currently sized to fit the tubes supplied by Wolfgang Hasper http://fer3.com/arc/m2.aspx/Borrowed-Bygrave-Hasper-jan-2016-g34233
- Some pieces such as the knob and octagonal top have internal recesses to hold imperial sized nylon collars which support the shaft for the locking mechanism.
Adjustments would need to be made for different tube sizes or metric inserts. It is a simple matter make such adjustments as needed in the openSCAD source code,
Regards,
Robin
