If printed properly this adapter will press into 24 well, 10 mL, storage plates (Agilent Technologies 201272). Intended for SLA printing with minimal additional post processing beyond remove support artifacts. For best results and simplest clean-up print up-side-down with the top of the adapter toward the build plate. Intended for use with plastic (PP, PS, PC) 16 mm test tubes which have a slight taper. For use with glass test tubes additional post processing is required (e.g. reaming with 16.25 mm drill bit or reamer).
