20mL Glass Scintillation Vial tray

20mL Glass Scintillation Vial tray printed on a CR-30 3D Print Mill. Included the FreeCAD drawing in case you wanted to chop it in half and print on a smaller printer. In order to adhere to Aeronautical regulations in regard to the transport of Ethanol, I designed this tray to contain the maximum amount of Ethanol allowed per exempt shipment. A description of the International Civil Aviation Organization exemption is available here: https://spnhc.biowikifarm.net/wiki/Shipping_and_Handling_of_Dangerous_Goods Essentially, the A180 exemption indicates that you cannot ship more than 1L of ethanol per package with no more than 30mL allowed per vial. Since 50 x less than 20mL = ~1,000mL you will safely fall within the limit when using the two tray halves to securely hold the 20mL glass scintillation vials securely. Simply collect your samples, in my case insects preserved in ethanol, drain any excess ethanol except for 1/2 to 3/4, secure the 20mL scintillation vial screwcap, apply a parafilm wax sealant to the lid, place in the tray, tape the two tray halves together, and place in a cardboard box with padding for transport.
