Rain Barrel Hose Barb Flange
A bolt-through bulkhead flange with a serrated 5/8 in (15.88 mm ID) hose barb, for tapping a rain barrel, IBC tote or tote-style water butt without a threaded fitting. 52 mm flange with four M4 clearance holes on a 38 mm bolt circle clamps a gasket against the drilled tank wall; the barb stands 34 mm proud with four ridges for a worm clamp, through a 10 mm bore, 40 mm tall overall.
2x3 Downspout Rain Barrel Diverter
A screw-on side-outlet diverter for standard 2x3 in (51 x 76 mm) rectangular aluminium downspout: cut a 58 x 34 mm window in the spout face, seal and screw this 74 x 84 mm flange over it with four #8 or M4 screws, and the 30 degree chute throws the flow sideways into a rain barrel lid instead of the flowerbed. The chute is a 64 x 40 mm rectangular tube with 3 mm walls, 58.5 mm tall as printed, gusseted at the flange so a full column of water can't snap it off — print in ASA or PETG for UV life.
