My daughter wanted a hobby horse obstacle. I made one from wooden 15mm diameter poles and some 3d printed connectors. The stick holders can slide up and down so the height is adjustable. 

Hadware needed:

• 15 mm pole - any other size will work as well but you will need to scale the print.

  • In my case I bought 3 x 2 meters length poles and then cut it to size

  • You will need sticks in 3 different lengths. Two in each length

    • 2 for base - the shortest. They slide through the base connector

    • 2 for the side poles. The longer they are the higher the obstacle can be.

    • 2 horizontal ones. I think it's good that they are at least 1 meter long to have enough space for jumping

Attached files:

There are 2 versions of the files. 

• v1 has 15.1 mm holes for the poles. The stick holders have very shallow cavity for the horizontal pole. It falls very easily. 

• v2 has 15.3 mm holes for the poles. The stick holders have less shallow cavity for the horizontal pole. It falls still very easily but is not falling when you place the stick on it. It was feature request from the user :)

Printing instructions:

Print one stick holder first. Either from v1 or from v2. It is the smallest part, so you will waste less filament and it will let you know how is the fitting between pole and the connector. Once you have some idea then scale it and print the next one. Once you have it scaled, print the rest of the files in correct scale.

The goal is that the holder can stand still on the poles but can also slide without much trouble when adjustment of height is needed. It is also possible to use small screw and tighten the holder to the stick. There is small hole on the side of the holder for this purpose.
