Modified to encase a small retractable tape measurer found here

for sewing and clothing that's flexible. I integrated a button on the side of the skull that can be pressed to trigger the button on the side of the measuring tape.

I may upgrade the model to use a bolt and screw to secure the two sides together or change it to be interlocking via puzzle like cutouts in the future as this is far from an elegant solution. But I wanted to avoid glue to be able to retain access to the tape measurer.

3D PRINTING SETTINGS

5-15% infill worked for me on a Bambu Labs P1P, used 5 line brim, tree supports on plate only and a gyroid fill pattern.

I believe I resized this correctly, but if it's too tight of a fit, try 102%
