Zip-Tie Top-Post Battery Terminal Boot
A cover for car, marine and mower top-post battery terminals that replaces the missing or cracked rubber boot. The open-bottom hood's inside measures 36 x 52 x 32 mm, so it fits over the post and clamp. A 13 mm U-channel takes battery cables up to about 12 mm OD, and a zip tie through the slot underneath holds the boot to the cable. It keeps tools from shorting the post and slows corrosion. Print it in red for positive and black for negative.

Boat Trailer 2x4 Bunk End Cap
A cap that slides over the rear end of a carpeted 2x4 boat-trailer bunk, so the hull slides onto a smooth chamfered nose instead of catching on frayed carpet and the cut lumber end. The pocket is 100 x 49 x 36 mm. Crush ribs grip a 38 x 89 mm board wrapped in roughly 4–5.5 mm of carpet, and there are three drain slots so water doesn't sit against the wood. Fix it with #8 pan-head screws through four 4.6 mm side holes, none of which face the hull.
Worm-Drive Hose Clamp Standoff Saddle
A screw-down V-saddle that raises a coolant, fuel, vacuum or bilge hose (about 15–40 mm OD) 18 mm off a vibrating firewall or hull. A standard worm-drive band clamp up to 13 mm wide, or a zip tie, passes through a 14 x 3 mm tunnel and wraps over the hose, so the clamp holds the hose in the saddle and never rubs on the panel. The base is 90 x 28 mm with two 5.5 mm holes for M5 or #10 screws.
