Stackable record drying separator (also a 7" adapter)

This is a vinyl record drying tool that lets you stack multiple records, so tat they do not need to be dried besides each other, when drying them after washing or applying wood glue to peel the unwashable dust out. You can use it as a standalone drying stand, but it's not super stable without the spindle from the previous unit inside. It is advised that you use this as the first layer of stand instead: https://www.thingiverse.com/thing:4783575 to make the whole tower more stable. Avoid stacking too many records if you choose to use the bigger stand as the first layer, as it might warp the first record a bit (unlikely, but theoretically can happen). It should also work as a 7" adapter. You can now print it with low infill because I added a little hole in the spindle to force the slicer to add a wall in there to make it stronger.
