Where do you keep the key?

The keyhole is on the CAD.

My next offering for the transition. The various other features of the stop valve etc are still to he done but I'll run a test print while I'm at work to see how it's going.
Not sure of sizing yet so I'll run this at 70mm high to get an idea.

Good enough. R-

Not a total disaster with the test print.
I broke the top when I dropped it fresh from the printer (slippery when wet). And the distortion of the base and lower part of the main shaft is down to insufficient supports snd poor model orientation in the printer.
So I'll change that and beef up a couple of sections.

Nearly there. Not 100% perfect but close. The arm is separate from the base so I can a) print spares without wadting resin on the base b) a couple of small details are a little fragile.
I can and will design alternative cranked arms that will fit.

That looks good. Will you make different shapes arms.

Working on it now Brian.
Will also do a shorter base for platform use.

Just for you Brian.

That looks just the job Steve.
