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.
Caulk Nozzle 45° Bead-Size Cutting Guide
This 100 x 30 x 36 mm block has a 45° knife ramp and five sizing holes for common caulk bead sizes: 1/8, 3/16, 1/4, 5/16 and 3/8 in (3.2–9.5 mm). Push a cartridge nozzle up through a 13 mm bore until it jams in the 3.5 mm sizing land, then slice flush along the ramp. You get a clean 45° opening at the bead size you picked, every time, with no guessing on a tapered tip.
Tub And Tile Caulk Tool
A one-piece 100 x 50 x 10 mm caulk finishing and removal tool for re-sealing a tub, shower pan or vanity backsplash: its four working corners are rounded to 5, 8, 12 and 16 mm so each one lays a matching concave silicone fillet while the two adjacent flats ride the walls of the 90° joint. The opposite side carries a 26 mm wide scraper blade tapered to a 1.8 mm plastic-razor edge for lifting old silicone off tile without scratching it, a narrow rake point for digging the joint out, and a 4.5 mm hole for an M4 screw or nail to hang it.
