Hi! I don’t have a handy anymore, so impossible to test myself, but I thought it would be nice and easy to adapt the SR6 “clamp mount” I posted a while back to the handy in case someone is interested. I’m just not sure of the exact diameter of the base of the handy. Perhaps someone can share the measurements if interested?
Anyway, the idea is you attach a sufficiently long bar-clamp to a plank, slide on the 3d printed mount and secure it using the bolt in the back. It can slide up and down so you can adjust the height very easily. The bolt screws into a recessed m8 nut which can be inserted from the bottom. Securing the handy in the mount can be done using an m3 screw and wing-nut.
Aside from the 3d printed part, the other components (50cm+ bar-clamp, plank, m3 wing-nut, 40mm m3 screw, m8 nut, 60mm M8 hex bolt) should be easy to source at any diy store.
