STANDARD (66mm) 12oz to 16oz Adjustable Can Holder

Update 2026-02-21: I made some minor print profile and geometry changes.  Original and Revised (v1.1) models will work together and be interchangeable.  Just trying to commonize some settings between my various models to what I have found to work the best now that I've printed a few of my own and for friends.

Update 2026-01-25: If you want something capable of holding a larger range of cans, I would recommend the NEW 330ml-500ml model!  It will also hold the 12oz and 16oz cans just fine:

Update 2026-01-12: If you prefer the thinner SLEEK size cans (57mm diameter), I uploaded a model for those also:

Introducing a 2-in-1 adjustable can holder for STANDARD size cans (66mm diameter)!  

I designed it with a twist Base to change what size can it can hold.  Twisting the base 180 degrees will raise or lower an internal platform for the standard US 12oz or 16oz cans.  

I wanted a single can holder for when I drink beer.  But often times the can sizes of what I drink vary from 12 to 16 ounces.  So I came up with this design as a way to adjust back and forth but keep the same “mug” as it were.  

I designed the exterior and handle to my liking, but I recognize everyone has their own tastes.  So within the downloadable files is the STEP file for the “bare minimum” core of the can holder that you may customize for yourself if you upload it into your preferred CAD software.  I recommend keeping your modifications to the exterior unless you think you have a good understanding of the internal workings.  

If you upload a version of your own to work with my mechanism, please credit me for my design!  And please send links and pictures!  I'd love to see what the community comes up with.

Lastly, of course, I will gladly welcome constructive feedback for future improvements or design ideas.  So please feel free to comment your thoughts or suggestions and I'll happily consider them!

To Assemble:

1. Thread together the Twist Base and Riser fully.  The Riser should bottom out in the Base.  
2. Insert the Base/Riser sub-assembly into the bottom of the Body of the Can Holder and apply gentle upwards pressure while turning.  

3. The three “slides” on the Riser should catch in their respective slots in the interior of the Body.  

   

4. Push firmly to seat, and the built-in clips should snap in and hold it in place.

To Disassemble:

1. Twist the Base clockwise (as viewed from the bottom).
2. You will feel resistance when it reaches the upper position for the 12oz can.
3. Continue twisting the Base clockwise (firmly) past this resistance and the Base will push against the Riser and pop free.
4. CAREFUL!  The Riser will be loose from the Base at this point and may fall.  Be prepared to catch it!
