Adjustable height shim

This shim can be adjusted up to around 125% its original height using a screwdriver. Each shim requires two of the pieces printed the same size, plus a #6-32 machine screw and hex nut set of an appropriate length. See instructions for details.

This can be used for furniture making (I developed it to fine-tune drawer slide rails), for leveling, etc.

Version 3 adds the option of screw holes so one or both sides can be attached - may be useful for woodworking applications.
