Magnetic Micropipette Holder for Efficient Lab Organization (Embedded Magnets)

This small modification just embeds magnets in an already good design. This will decrease your holder's strength of attachment to the wall but removes the danger of pulling out the magnets if they are improperly glued into the model. If you want the magnetic attachment to be even stronger, you can decrease the layer between the magnet and the edge to just 0.1 mm to make it one layer of plastic. If you have difficulty with it sliding, you can either print it out of TPU, print just the first layer out of TPU and the rest from PETG, or spray a rubber adhesive on it like Flex Seal.

Embedded rather than glued magnets.
