Wobbly Chair Dowel Hole Rebuild Sleeves
A snap-off sprue of six crush-ribbed sleeves for rebuilding wallowed-out dowel holes in chair and table joints. Drill the worn hole out to 12 mm and glue in an 8 mm sleeve (25 mm long, 8.3 mm bore), or drill to 14 mm and use a 10 mm sleeve (30 mm long, 10.3 mm bore). Six 0.3 mm crush ribs bite into the wood and leave channels for the glue, and the chamfered nose starts the sleeve straight in the hole.
1 in Wire Shelf Post Split Sleeve Pair
Replacement wedge-collar sleeve pair for 1 in (25.4 mm) wire-shelving posts (Metro, HDX, Whalen/Costco, Seville style), printed upright and joined by two snap-off tabs. Bore is 25.6 mm with a 2.6 mm wide, 0.8 mm deep internal rib 15 mm above the base that drops into the post groove; the outer taper runs 28.8 mm at the small end to 34 mm at the top over 46 mm, so any shelf collar whose bottom opening passes 28.8 mm wedges and locks as it slides down. Print one pair per post position (four pairs per shelf) to re-hang a shelf whose original clips cracked or went missing.
Office Chair Caster Socket Repair Sleeve
This sleeve repairs a cracked caster socket on an office chair base. Drill the split socket out to 16 mm (5/8 in), then epoxy the sleeve in place. The 11.2 mm bore takes the common 11 x 22 mm grip-ring caster stem, and the 28 mm tube is longer than that stem. A 32 mm washer flange spreads the load across the underside of the leg. Three V-grooves hold the epoxy.
