Olympic 50 mm Bar Pinch-Bolt Collar
This split-ring collar fits a 50 mm Olympic barbell sleeve and replaces spring clips, which get lost, slip under load and pinch fingers. It has a 50.6 mm bore, a 66 mm OD and is 25 mm tall. One M5 x 25 bolt pulls the jaws shut, with its nut held in a captured 8 mm hex pocket.
Door Gap Resistance Band Anchor
A no-drill T-shaped anchor that goes through the hinge-side gap of a closed door. It lets you clip resistance bands or a carabiner to any door without screwing anything into the frame. The 2.4 mm thick, 40 mm tall tongue passes through the gap. A 40 x 10 mm stop bar bears on the far side of the door and jamb, and an 18 mm eye on your side takes the band. The tongue reach clears doors up to 48 mm thick, and the part prints upright so the pull runs along the layers instead of across them.
Stud-Mount Olympic Weight Plate Horn
This wall horn screws flat to a 2x4 stud face (38 mm, matched by the 28 mm-wide backplate) with two #10 wood screws (5.5 mm holes, 102 mm apart). It holds 2 in Olympic plates (50.8 mm bore) on a 30 x 28 mm I-section horn that angles up 8° and ends in a stop lip. The part prints on its side, so the bending load stays in the layer plane instead of peeling layers apart, and it replaces a $60 steel plate tree with one 130 mm-tall bracket.
