This is the toploading hypo used in Season 3 of Deep Space Nine 'The Adversary' when performing blood tests to identify Changelings. There is a hollow version with a trigger that can activate a switch. There is a solid version. Vials can use magnets to be removable and hold in place. Can use glass vials 15mm diam. x 85mm long. There is also a printable vial. Free test tube rack included. Files are .stl

Personal use only

• I have added an updated version of the vial top cap. this one will fit inside a 15mm test tube without splitting it apart!

• Also added a thin ring you can put on the test tube to simulate the sliver of white tape wrapped around it. Simply print it in white resin for best results.
