Several of you have inquired about coupler pockets from my PS2CD4427 project. I’ve looked into it & here’s what I have come up with.
These are not intended to be used as-is, but a pattern for mold making - hence the hollowed out part of the center sill. The cost for one copy from Shapeways would be $45-$50 in “frosted ultra detail”.
They are designed to work with Kadee #1 scale couplers.
If there’s any interest, I can make them public in my Shapeways store.
