This build platform funnel is designed for users of the Form 1 (also the Form 1+), to let the resin that is soaked into the build platform during long prints, leak out of it. This funnel consists of two parts; the upper funnel part and the foot, which the funnel can be place on onto a plastic cup. For the complete story, please visit the thread on Formlabs' forum: http://forum.formlabs.com/t/build-platform-funnel/4613 Besides the STL files, I included the form files for owners of a Form 1 (for quick and easy printing).
