A 20° angled stand that tilts a solderless breadboard toward you for better wiring visibility, with a 163 x 25 x 7 mm parts trough in front for resistors and jumpers. The 172 mm wide deck takes a full-size 830-point board or two half-size boards, held by a 4 mm front lip and an 8 mm rear backstop with three 14 mm notches for jumper bundles; two M3 clearance tabs let you screw it to the bench. Overall 172 x 108 x 38 mm, open-ribbed underneath so it prints without supports.
A palm-sized sanding block with a flat 88 x 68 mm face and a contoured grip; a quarter sheet of sandpaper wraps the bottom and tucks into the two tapered slots on the end shoulders, which wedge tighter as you sand. Hollow-cored so it stays light and cheap to print.
A flat lever wrench whose toothed V-jaw bites any lid from about 21 to 72 mm across, so a stuck jar, bottle or pill cap pops with wrist leverage instead of hand strength. 126 mm long, 9 mm thick, with a hang hole in the handle.
