I watched the Mission Impossible the other night where they have the suction cups for climbing glass.
It was much easier to do this mod in PS than get into cad. Sometimes i forget how powerful PS really is.
Magnets should just push in snugly, no glue needed for my applications.
I printed these at .1mm layer height, but i doubt that's necessary.
Let me know if these don't import correctly. it should have 3 added volumes.
The author remixed this model.
These were the original grip hands, I used PS to add and remove some material to allow the installation of a 6x3mm magnet.
