parametric spool adapter (AMS lite)

A simple, but flexible spool adapter for the AMS lite and spools with a big inner diameter (~73mm). This adapter is quite flexible and thus fits various spools with slightly different inner diameters around 73mm. This model also comes with a scad file, so you can adapt the adapter to different sizes. The difference between inner and outer diameter should probably not exceed about 30mm though. Printing: use vase mode and a line width of 0.8mm (a 0.4mm nozzle is fine).
