I added a print pause at 19.6mm print height. Inserted a 3.2x3.2mm magnet.
I needed another print quickly and didn't calibrate for a new filament …
My magnet was just slightly loose. If it's too loose it can attach to the print head and ruin the print. My solution is to put a drop of accelerator on the magnet and a drop of CA glue in the magnet hole. A steady firm push and a few seconds … continue the print no problem.
Carefully trim the printed braces. If the surface has any irregularities, a file or xacto blade can clean it up quickly.
The author remixed this model.
Added three printed braces to help with print stability after magnet insertion.
