MX Switch Squeeze-Puller Flexure Tweezer
A one-piece flexure tweezer for pulling MX-style switches out of a hot-swap board. The hooked prongs rest 15.4 mm apart and close to about 9.5 mm before a built-in stop, so they cover the clip tabs on either side of a switch in a standard 14 mm plate cutout. It's 99 mm long and 5 mm thick, and prints flat so the squeeze force runs along the layers instead of across them.
Flexure DIP Chip Extractor Tweezer
A one-piece flexure tweezer for pulling DIP chips (roughly DIP-8 to DIP-28, 0.3 in body) straight out of sockets. Its 1.6 mm hooks slip under both ends of the chip so the pins come out without bending. At rest the hook tips are 36 mm apart, and built-in squeeze stops keep them from closing tighter than about 7 mm, so you can't pinch the chip body. The whole tool is 100 x 50 x 6 mm, prints flat and has a 5 mm hole for hanging it on a pegboard hook.
Flexure Sideswiper CW Morse Key
This is a one-piece single-lever sideswiper ("cootie") Morse key for ham radio. The key lever swings on a 1.8 mm printed flexure blade that bends sideways in the XY plane, so no bearings or springs are needed. Two contact posts take M3 brass heat-set inserts (4.0 mm bore) on a horizontal axis. M3 contact screws with lock nuts set the gap to an M3 screw and nut pair through the lever's 3.4 mm hole. A third M3 insert at the back is the common terminal. The 110 x 70 mm base has two 40 x 18 x 5 mm pockets that you fill with washers or lead shot for weight. Put 2 mm stick-on rubber feet under the base so the lever clears the desk.
