F!RST Layer

Print in place articulated first layer height gauge.

**Design**
Tuning the first layer is challenging at times! Once you manage to level the bed, adjust nozzle distance it looks nice and works as it should. But is it really the thickness it should be? Will the overall height of your print be on the point? Since extrusion width as well as flow settings play a role (not only) in the first layer as well we always found it useful to measure the effective height and do some additional tuning and dialing btw. nozzle distance, flow and extrusion width. Doing that with a caliper was always a bit complicated and unreliable (directly on the bed) so we designed a quick tool to measure the first layer's thickness directly on the bed.

**Construction**
The indicator needle is articulated at the left side and relates to some simple notches at the right side, each indicating a 0.1 mm step. The frame has a flat surface for stability and a ruler / guide like bottom to place it flat on the print
