Hi folks,
 this might be quite interesting for the folks that miss front panel
 switch handles!
 As some of you might know I'm currently working (a bit) on a new batch
 of Omnibus USB boards. And I have announced that there will be a kind of
 handle for the boards this time... I went to my neighbour and showed him
 some bits and pieces. He has a nice little workshop for concrete artwork
 (
https://www.fritzundfranz.com/) and spent a lot of time into perfecting
 his moulding skills.
 I gave him a pdp8/e yellow switch handle with broken axle (usual
 problem) to try what can be done.
 Today I came home and he gave me the piece saying that he was unable to
 replicate it. I took it (a bit frustrated) and stated that he has
 somehow ruined the surface... Haha! It was the replica!
 He told me that this was a first "fast" shot including a "rough"
 approximation of the colour.
 I was stunned!
 Here you can see pictures. Even the defects of the original have been
 replicated.

 He told me that it was a bit difficult to get the holes at the side
 right. I think that it would be no problem if they'd be more shallow or
 even gone.
 * His material is less translucent than the original. Won't probably
 change. So a perfectionist could spot the difference.
 * He states that he can hit colors even better! (Think of the special
 colors!!!)
 * The axle stubs would be omitted and made of steel (something I already
 plan for repair of that weakest point)
 * He is able to produce flawless finish (remember: it's a raw prototype!)
 This is not my business. I told him that I'd ask around if there would
 be serious interest. He is not in vintage computing and does not work
 for free. So one piece would probably cost around 5-15 EUR each,
 depending on demand, color etc.
 Please give some feedback!

For a prototype that looks very nice indeed!
I agree that for this level of molding precision the pivot axle would be better
if done as a separate piece and press fitted. Steel would be fine, brass rod would
also be ok and softer to machine. A small jig could be made to cross-drill the
hole accurately. Same for the side holes just using the depression as the centre
point.
Your neighbour has done an excellent job there, well done. He ought to run off a few
different DEC paddle switch designs and flog them on eBay :)
