Soldering aid - clamp with simple internal magnetic base

I really wanted to make this work without the TPU base as i dont have TPU. And I only plan to use this on a metal sheet instead of its family of tools. So made this simple remix in tinkercad. The updated base has a 11mmx2.2mm hole inside the base starting at .3mm height. The cavity is perfect for my 10mmx2mm magnet discs. The slightly larger horizontal space also makes it easier to place during print and the vertical space is small enough to keep a tight feet after the layers printed. Use the original moving part of the clamp. I also used rubber band instead of metal clips, they work remarkably well for my use case.
