Loved the Low Poly Pineapple by Print Ninja but needed it upside down for...reasons. IYKYK.
It's deliberately a loose fit to accommodate different printers tolerances. A few drops of gel CA in the pineapple, flip it over, and stick it in. They've been holding up as decorations at parties and for our friends. For the best quality print, use the STP. If you don't care, use the STL.
