Oil Drain Plug Crush Washer Peg Caddy
A 150 x 70 mm drip-lipped bench caddy for oil changes. It has four 30 mm stacking pegs for M12, M14, M16 and M18 drain plug crush washers, each 0.6 mm under the washer bore so they slide on easily. Notches in front of each peg (1 to 4) mark the size. A 34 mm cup holds the hot drain plug while the oil drains, and the 8 mm rim catches drips.
Flagged: automotive electrical. Not for safety-critical use without independent engineering review.
Universal Fir-Tree Kayak Scupper Plug
A barbed, tapered plug for the drain holes on a sit-on-top kayak. Six stepped barbs cover any hole from about 24.5 to 44 mm, so one plug works in scuppers of several sizes, and the same design keeps working after the kayak's own plugs go out of production. It has a 54 mm flange with a lanyard ear (5 mm hole), is hollow to keep it light, and has a grip bar in the cup so you can pull it out. Print it in TPU or PETG for the best seal.
