Making custom stems

[Wildcard]

I've been slowly designing a custom MX stem that fits inside a shell type key cap cover (IBM caps are the perfect example).



I was originally looking to mold these out of some type of plastic, but I know the cost for the mold will probably be pretty high.  My other options are 3D printing or possibly making a 2 part silicone mold and using some type of epoxy, however I wonder how well this will work with such a small part.  Basically the final product will look like a small cuboid with an MX stem protruding out one side. You can insert it into a shell key cap cover with a dab of glue to make it permanent.

Can anyone suggest a good method to make these?

After doing some digging I also found that that binge and photekq are also working on creating custom stems here, except I'm custom making it to replace an existing stem to fit a key cap for a much older keyboard.

I'll be closely following this thread for ideas on how to properly mold perhaps. This stem is very detailed towards the base. Hopefully I can make a working prototype.

I think that Mr Interface also has a project going on to make Cherry MX-compatible key stems that take IBM keycaps.

It seems like a really good idea to bring life to these old key caps.

I guess I should try to finish my prototype and go the epoxy route.
