M5 Screw-Press Walnut And Pecan Cracker
A screw nutcracker that sits flat on the counter. The 90 x 52 x 24 mm closed frame holds a captive M5 hex nut. You drive an M5 x 60 socket-head bolt with a 4 mm hex key, and it presses walnuts, pecans or hazelnuts (about 10–50 mm) into a V-notch anvil. The pressure builds slowly, so the shell cracks and the kernel stays whole, and the walled tray keeps shells off the counter. The frame prints lying flat, so the cracking force runs along the layers rather than across them.
M5 Thumbscrew Card Scraper Bowing Holder
A 140 x 24 x 20 mm handle for a flat cabinet card scraper. The scraper stands in a 1.2 mm slot that runs the full length and is open at both ends, so it takes blades 0.4–1.0 mm thick and 120 mm or longer. An M5 screw goes into a captive M5 nut (8 mm across flats) and pushes on the middle of the blade so it bows into a 3.2 mm relief, which sets the curve without heating your thumbs.
M5 Screw Flexure-Pad Guitar Capo
A one-piece screw capo. An M5 bolt runs through a captive nut and presses on a pad hung from a 12 mm living hinge, so the bolt tip never touches the neck finish. The pad tilts up to clamp necks about 16–25 mm deep (fretboard plus neck) inside a 68 mm wide throat. The frame prints flat, so the clamping load runs along the layers, and a 2 mm recess on the bar takes a 10 mm wide rubber or felt strip that sits on the strings.
