Backer Rod Seating Roller For Tub Joints
This is a print-in-place roller with a 52 mm wheel. A 4 mm wide tongue on the wheel stands 6 mm proud of the wheel body, so foam backer rod gets pressed to an even 6 mm (1/4 in) depth in tub-to-tile and shower caulk joints that are 5 mm or wider. The wheel spins on a captured double-cone hub with a 0.42 mm running gap. It prints in one go with no supports, and the 166 mm grip has a hang hole.
Shower Door Top Roller Hanger
Replacement top hanger for framed sliding shower doors whose original roller cracked and whose OEM part is long discontinued — a 624 bearing (4 x 13 x 5 mm) becomes the wheel, clamped on an M4 x 20 screw through the 4.5 mm axle bore, so the outer race rolls on the existing track. The 64 x 24 x 5 mm plate carries two 4.6 x 11 mm slots giving 10 mm of height adjustment to re-square a dragging door, and the M4 screw head recesses 3 mm into the back so the plate sits flat against the door stile.
