About this model

If you know, you know. That polishing compound is expensive, so I made this to make getting every last drop easier. Scaled the remixed 24/415 cap threads to fit the bottles from ELM and put them in a cylinder with a two way funnel in PrusaSlicer. Thanks, Noupoi. Printed on Core One in Prusament PETG: Satin sheet. 0.15 STRUCTURAL profile in PrusaSlicer. 20% gyroid infill. 5% ironing because symmetry.
