Eye Dropper Bottle Stand

I made this so I could easily fill eye dropper bottles. There is also a cover, for transport. I also got SOOOOOooo tired of screwing the little lids on. So, I made a 1/4" drive, so it can be used in a little screw gun. I also made a pocket for a tiny neodynium magnet. The magnet is 4.4mm X .8mm, with a bit of epoxy underneath. I attached a screen shot to show, how I made it a 1/4" drive. Grab some sort of nut.stl and reduce in size till you see the tiniest portion of the shaft, as shown. No supports are needed. If you need this done in 100 bottles, I have that too.
