Extension feet for Stokke Tripp Trapp high chair to prevent tipping over. Works at least with older models, please let us know if you have fitment issues. Boost Me Please consider leaving a Boost to support release of free high quality models. Print from strong material, avoid e.g. PLA Matte or PLA Silk. We used ABS. The fitment should be tight. Scale the model according to the shrinkage of the material you are using, e.g. ABS and PC shrink considerably. Test that the feet fit the chair. They need to be snapped in place and some force should be needed. Tap gently with a hammer if needed - for us, a firm push was enough. Install heat inserts to locking nuts. Place the locking nut in the holes of the chair. Align the flats with the legs as indicated with the orange lines. Place the feet on the chair and lock in place with M3x10 or M3x12 countersink screws. No need to over-tighten, stop after you start feeling increase in resistance. To protect the floor, place felt pads over the screw heads. Disclaimer: This print is designed to increase safety of the chair but cannot guarantee it - use your own discretion and always attend the child when the chair is used.
