I just did. Had a spare beast stick and an extra 18” feather stick drilled from a cam cleat already. I had bought a EWO Ultimate One Stick in 18” and then bought a 12” feather stick when I realized I wanted it more compact.
I took a hacksaw and cut it to 12”, drilled holes for the steps/standoffs. I added a cam cleat, Amsteel rope, 1/4” cable clamp to keep the rope from moving, and sewn 3 step 15” aider from EWO. Also bought a pack-n-play pouch for the aider.
