Stackable Sanding disc holders w/ alignment posts

This model is simply 2 different models assembled in Orca Studio. I wanted stackable sanding disc holders, but I always wanted some guiding posts so I could press the sander down onto the discs and end up with aligned vents. For this first iteration, I have to press harder than I expected to get the discs to stiick properly to the sander. I think the alignment posts are too tall. Unfortnately for me, I printed 4 of these before I tested the actual mounting of the disc. You could scale the Z axis by 80%, but it'll make the numbers look weird. Or put something springy below the sanding discs – maybe a sponge or a couple of layers of packing foam stuff. Something that pushes back up a bit. I still need one more of these, so I'm going to try to tweak the design a bit.
