Remix of Kinetic Sculpture to fit on Refrigerator with Magnets

I liked this Kinetic sculpture https://www.printables.com/model/289583-kinetic-sculpture , but didn't want to tape it to the wall & realized I could use magnets on the base & place it on the side of the Refrigerator. I am using 10x2mm disc magnets & I knew the original design was too heavy for the magnets. Since the author generously uploaded the step file, I set out to modify the design to cut down the weight. I made a Org_Arm_Rnd_Long.stl, Org_Arm_Rnd_Medium.stl & Org_Arm_Rnd_Short.st l to match the connection on the hubs. I printed 24 of the Org_Arm_Rnd_Short.stl file using the original parts of rest of the design with the exception of changing the base the hold magnets. It was still too heavy. I decreased the thickness of the arms by 2mm, which allowed me to change the thickness of the spring, hubs & top of base. I also changed the spring from .8 to .9mm thickness & added some reinforcing at the dovetail joints as the 1st print broke at one of those joints. I changed most of the tolerances to .2mm as my printer works better at those tolerances. I used fusion 360 for most of these design changes. I still had a problem with filing the cover to fit in the base, so I decided to use threads for that & openscad is my choice for any parts with threading. Fusion 360 does not have an easy way to give tolerances to threading & openscad excels at this. After testing some different threading, I used a non-standard M8 thread size for the cover & base. The cover I changed to a simple hex nut to cut down on printing & seems to work well. The tolerance I had between the threads was .3mm (Gap=.6 in openscad). To print this Magnet Based design, print the following files. 1 - MagneticBase_8_25mmID__Rev4.stl 1 - Hub1s_Mod.stl 1 - Hub2s_Mod.stl 1 - SpringS1_Mod.stl 24 - Arm_Small.stl or 12 of Arm_Small_2x.stl or 4 of Arm_Small_6x.stl 1 - CoverHexHead_7_65mmOD_Rev4.stl (for .3mm thread tolerance) (10 minute print or less) or CoverHexHead_7_75mmOD_Rev4.stl (for .25mm thread tolerance) or CoverHexHead_7_85mmOD_Rev4.stl (for .2mm thread tolerance) or CoverHexHead_7_95mmOD_Rev4.stl (for .15mm thread tolerance) or edit MagneticBaseCover_Rev4.scad to what you need. If you use the openscad file you will also need to download the threads.scad from https://dkprojects.net/openscad-threads/ & place it in same folder as MagneticBaseCover_Rev4.scad I included the required .stl files to print this along with the fusion 360 file of assembly ( KineticS1_Assembly_Exploded v1 v5.f3d ). The assembly does not have the threaded base & cover, but style similar to original design. I also included the rounded arms I modified to fit the original design if you want to use those ( Arms_Long_Med_Short v5.f3d , Org_Arm_Rnd_Long.stl , Org_Arm_Rnd_Medium.stl & Org_Arm_Rnd_Short.stl ). This design can also work sitting on a flat metal plate like a steel picnic table, but not as well as hanging vertically. The magnetic base has room for 25 of these magnets. Think I left 6 of outside magnets out. Here is a short video of it spinning attached to the Refrigerator.
