Portable dog jump

thingiverse

I wanted an easy to transport jump for dog training. Two 8mm diameter poles and a cross piece, two printed clips and that's it. The central hole is designed so that if the clips are not perpendicular to the pole, they will easily slide up and down allowing fast height adjustment, but once pushed to be square with the pole the clips will secure in place with a friction fit. Lift the tip of the clip, set the height, push it down perpendicular to the pole and they stay put.
