A simple hook designed to hang a flat object (Busy-Board or Easel) to the rungs of a Pikler style climbing frame. Modeled specifically to fit the KinderFeets branded frame, however should fit any frame with 25mm rungs. The screw holes are countersunk - and the STEP file is included should you wish to adapt if to a different rung size. The mounts can also hang from the rope side, however the fit is not as snug.

The mounting plate is not tangent to the edge of the curve - resulting in a small hump which adds a little bit of extra grip to the hooks.

The example shown is printed with Polymaker Polylite ABS at .2mm layer height. Higher layer heights should work for faster print times. 

Obviously take care when mounting anything to kids play equipment - these are not designed for permanent mounting, they won't disconnect with lateral force and require the mounted object to be lifted off the rung - supervise your kids!
