In between my adventures in Panel Land I also looked at PDP-8 switches 
and other items that could be 3d printed. I came up with the following:

         1,  For replacing one or two missing switch levers 3d printing 
is ideal.

         2,  I believe the plastic to be ABS

         3. For example LEGO bricks were ABS, They are now changing to a 
greener type of plastic.

         4. Matching the colo(u)r might  prove interesting.

         5. For those who need larger quantities then good old injection 
moulding is still the best way to go.

         6. Mould making costs used to be high but modern CNC machines 
can do the job in short order.

         7. The split line on a PDP-8 lever is clearly visible. This 
shows they were made in a two part mould.

         8, How many per mould were there I don't know but say ten would 
not be beyond even small machines

         9. As soon as I get to a ship from stock situation on panels I 
might  revisit switches.

         10. And finally .. would I trust the Chinese?  Probably not!
