This is a magnetic door catch — keeps the door open using the magic of magnets ✨
The small flat part goes at the bottom of the door, and the big part gets attached to the floor.
The attachment is done using small nails.
Both models have a 8x3mm hole inside to insert a neodymium magnet.
Print the floor part so that the flat surface is printed horizontally (on the print bed).
Use a slicer plugin to insert a pause so that you can insert a magnet inside the printed part.
