Yes. After learning that BAWR wait time is 6 months AND the observation that JLC3DP SS printing is a similar price, I started designing a cage:
It is based on a BA-25 which I have, but I find to be a little too large and the end bars create odd bumps. Also on a cheap PA device who's size I like but it has a domed end which traps urine.
The design is very parametric. I can adjust the major dimensions by changing some numbers. I've done it in FreeCAD, which has some problems but great value.
I've started with a PA pin from the domed device and designed the cage around that. This requires that it be longer than I intend but it lets me do some home prototype prints. I could then print the cage and ring in nylon, which would be quite light.
Or I could scale it back to the size I want, then print the pin only in SS, clean that up and continue prototyping around the pin. Shapeways cost for a SS print of the pin was $160.
It is a project, but I'm pleased with progress so far.
