reference shim
thingiverse
To gain a better understanding of our various PLA filaments' appearance, we created a small "shim" that is printed in each color. This shim remains with its corresponding spool, threaded onto the filament, even during printing (as shown in photos). We designed this using SketchUp and export2stl plugin.
