This is for my dry box.
some may use it for fun
u can also copy that and do what u want
spins great

U also need:
2 608 bearings
2 m8 nuts
1 150mm m8 rod
2 washers (od=15mm)

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/aJaybMc5uyu

to make it easy to assemble I made a bolt out of m8 rod an a nut, usind torch and solder (the total measure with the hat is 150mm). I also glued in place the nut underneath the base. so u put all the components on a bolt and then insert it into the base.
