@LabOnTheCheap We build a magnetic tube rack for DNA extraction and wanted to share the stl file to all interested in 3D-printed lab equipment. “
And here’s the link to the STL file hosted on the NIH 3D Print Exchange. It’s crazy that these devices are often sold for hundreds of dollars. Neodymium magnets are cheap, and even if you don’t own or have access to a 3D printer you can use an online 3D printing service to print this for around $50.
When asked about the magnet, Gabriel says
@LabOnTheCheap Super strong neodymium magnet N24 4 x 1/2 x 1/4 from applied magnets store on Amazon. $7.59 each. One for each side. “
