This is only two of the parts for the painting handle. Follow the link to the origin model to get the rest of the parts.
I redesigned to adapter top and figure base for the Ratcheting miniatures painting handle.
I wanted the adapter and figure bases to use smaller magnets, since 10mm magnets are too strong and more expensive.
I also wanted one magnet size, dont know why the original uses 4 and 5mm tick magnets.
I changed the cross slot to a bevelled star pattern to make it easier to slot in and moved the magnet to the bottom of the figure base, to enable attaching the magnet on a metal plate when the figure base is not on the painting handle.
You can modify the models on OnShape by changing the variables if you want to change the magnet size:
