YETI 16 oz. Adapter/Extender (Customizable)

thingiverse

This is an extender for a YETI 12 oz can Colster coozie so it will fit a 16 oz or "Tall-boy" can with a snug fit. The extender fits between the insulated base of the Colster and the slightly-elastomeric ring that attaches to the top and holds the can in place. The threads follow the same split layout as YETI, with the pitch carefully adapted to be the same as well. It is very easy and smooth to screw onto the base. If desired, there's a sketch in the f3d file to add your own custom message (e.g., name, initials, etc.) but there's also an STL with "No Text" if you just want a plain adapter with no text - or if you don't have Fusion 360 to modify the text. Note: YETI recently updated their Colster design that has more of a curved/filleted top lip. I haven't tried this adapter with their new design, but I imagine it may have fit issues due to a change in the threads. Take a look at the photos to check which Colster you have (they're pretty different so it should be fairly obvious). Printing: Printed with PLA in .15mm layers seems to work fine. Support at the base (including a brim) seems to help it adhere to the plate better since it's relatively thin at the base.
