I played about some more and have made a version that, as per Julian’s suggestion, has the male dovetail on the slider. It’s a slightly more complicated model, but it prints nicely and I’m quite pleased with it. The clamping part needs some work still, as it’s not as strong as we’d like, but I think it’s converging to a relatively neat solution.
