Magnet holder for Eppendorf tubes

Ever wondered why Eppendorf magnets are so expensive?! me too :D

This is a remix of the referenced design (by user gujo) with the following changes:
-The Eppendorfs are closer to the magnets
-The place where the tubes are inserted has been re-designed so that there are no structures between the magnets and the eppendorfs, making the separation more efficient.
-There is no hole under the structure.

The design has been made for 25 x 8 x 3 mm neodimium magnets. Because the structure that holds the magnets has been minimised, it is important that the magnets adjust snuggly so that they don't start jumping out and binding to each other. Depending on the printer you use, you might have to modify the size of the holes or the settings.
