Shop Vac Hose Bolted Clamshell Splice
Bolt-together half-shell (print two) for repairing a cracked 2-1/2 in shop-vac hose. Cut out the damaged section, butt the two ends together and clamp them inside a 90 mm long sleeve. The bore has eight 45° buttress ribs that bite into the hose corrugations: 59 mm at the rib tips and 63 mm at the root. Each half's split face is shaved back 1.5 mm, giving 3 mm of squeeze when you tighten three M5 x 25 bolts into captured-nut pockets. It suits corrugated hose with a crest OD of roughly 60–63 mm, so measure your hose before printing.
Door Lock Rod Lap Splice Coupler
A 50 x 18 x 14 mm splice block for a snapped car door lock or handle rod. The two broken ends slide into parallel 5.3 mm bores from opposite ends, overlap by 40 mm and are clamped by four M3 set screws in brass heat-set inserts. That fixes a door that won't lock or open from inside without buying a whole handle assembly. The bores take any round rod from about 3.5 to 5 mm, so it also joins mower, choke and throttle linkage rods.
