Summary

Simple agility jump cup for NZ jump poles (1" schedule 40 PVC pipe, approx. 34mm external diameter).

Two models available - a screw on/stick on version, and a version designed to have a 20mm x 3mm neodymium magnet embedded into it, for use with magnetic jump uprights.

I printed mine using 95A TPU. I do not recommend PLA or other hard plastics for safety reasons. Do not give your dog the opportunity to ingest the magnet version!

When deciding where to put the screw hole on your gear, take into account the size of your pole. For a 1" pole (34mm dia) the screw hole needs to be 17mm below the intended jump height. i.e. for a 320mm bar, the screw hole should be set at 303mm to get the correct height.

Consider adding some double-sided sticky tape to prevent the jump lug rotating around the screw. Or if you have super sticky tape, you may not even need the screw.

There are two magnetic versions - one which completely embeds the magnet, and one that leaves the magnet accessible. I found that the embedded version held better - I think because the additional friction from the extra rubber outweighs the loss of magnetism from having the rubber there. If you opt for the accessible version you will need to glue the magnet into place.

In BOTH magnetic versions, you will need to pause the printer just before it prints the layer that goes over the top of the magnet. Ensure the hole is clean with no stringed bits of filament passing through it, then firmly press the magnet into place. It should lay flat, or be slightly recessed. Then apply a layer of glue stick to the magnet, otherwise the TPU will likely not adhere to/bridge the magnet.

If you are printing the glue-into-place version, pop the magnet out of the hole, apply a little superglue to the hole, and push the magnet back in. Printing the glue-in-place version with the magnet IN results in a really tidy hole for the magnet and you don't have to worry about bridging/supports for the hole.
