Lyson motor conversion kit adapter

thingiverse

This is a coupling to mount a lyson basic line motor conversion kit (https://lyson.eu/czesci-zapasowe/3067-electric-drive-for-minima-honey-extractors-dedicated-for-lyson-extractors-5903661506698.html) on my (or any) honey extractor that is not made by lyson. I have included the openscad file so it can be modified to other dimenions (most notably the holes to mount it on the extractor itself). I have mounted it on my 400mm extractor with great success. Just disassemble the hand crank and gearbox from the extactor, drop two of the bolts from the gearbox (m8) in the hexagonal holes of the coupling, and mount the motor with the supplied M12 nuts and washers. then place the assembly on top of the extractor with the m8 bolts through the top of the extractor lid, and screw on and tighten the m8 nuts. You still need to make a coupling for the shaft itself. I did that by making a T-shape from a square rod, with a slot in the top, and a strip of metal as the cross inserted in it, and welded together. Second I slid over a piece of steel pipe that would fit over the axis of the sling cage in the extractor, and cut a groove to accomodate the pin in the axis, and welded that together (on the square rod). I don't think printing a coupling for the shaft would be strong enough (but if you do, and successfully have, let me know). In retrospect, I should have made the nub where the catch for the lid goes 1-2 mm wider/thicker so the screw does not damage the surface on the opposite side, but I can't be bothered with printing it again. Placing a thin washer under the screw head would also work.
