Drip Line Twin-Lane Zip-Tie Ground Stake
This 150 mm garden stake has two V-lanes in its head. The wide lane takes drip mainline about 12–20 mm OD, and the narrow lane takes small feeder tubing about 5–8 mm OD. A zip tie up to 5 mm wide goes through a channel under both lanes, wraps over the tubing and locks the line down so it can't blow out or get pulled up. It prints flat with a T-ribbed spike, so the bending load runs along the layers instead of across them, and it's stiffer than the bagged stakes that snap.
