A base plate for 32mm OD LDPE airseeder hose together to form an arch.
It's a pretty good fit, not tight not loose, but I put holes in so you can screw your airseeder hose in. There's 4 spaces for pegs to peg it to the ground, 3 spaces for cables to exit.
You can string them together with a length of fishing line to keep the arch shape.
Arch-Foot-2 is probably the version you're going to want with the extra screw holes, it turns out, at least in Australia, the LDPE gets hot, expands, and gets slippery, sliding out the top - one hole was just not enough.
