A two parted gecko model which can be assembled to a single one and with the option to glue in some magnets. There is a option where you can insert the magnets that they are directly visible from the bottom and one version, that they will be glued in the upper part that they are not visible and will not make scratch to your fridge, but with the 0,4mm more distance the holding force will be a bit less. I recommend to use neodym magnets like N50 or N52.

Just print both models in different color and assemble them together.

If you print both models in two colors, you have a gecko pair with swapped colors like shown on the sixt picture ;-)

There is a small gap between the two parts for easier assembly. Also the cutout for the magnets is a bit bigger, that you can add some glue.

For better assembly, there is a model with chamfer on the sharp edges to avoid problems with elephant foot.

I used on my Elegoo Neptune 4 Plus the Prusament PETG Orange and Galaxy Black with 0,2mm layer thickness, 3 perimeter and 10% gyroid infill.

Would be happy to see your makes!
