I really like the idea to print a handle for beverage cans to keep the drinks cool and your hands warm. But all of the designs I found for the 500ml can required glueing a strut to the bottom to prevent the cans from slipping.
So I designed my own can bracket/handle with a much tighter fitting to render an extra strut obsolete and cut down in printing time, material, postprocessing and ease of use.
I tried to keep the additional width small so the can still fits the holders in conventional camping chairs with the handle attached.
The can slips nicely into the holder. Removing is a bit trickier when the can is not open but quite easy when the can was emptied (the idea is to drink up anyway before removing the can)
I tested the handle with some energy drinks, bembel (apple wine) and a few beer cans. Albeit there seems to be a small height difference between some cans (~0.5mm) the handle can be attached tight to all of them.
I printed the handle in the picture with 0.2mm resolution, 20% infill and supports for the handle.
Even thou this design works quite well I already have some ideas for improvements and may add and optimize some parts of this in the future. Ideas are welcome.
Update on 24.06.2019:
- While on a hiking trip we notices that the lid may interfere with sunglasses, so I added a second lid (Lid2.stl) than can be opened wider.
Update on 18.06.2019:
- Redesign of the handle (more sleek)
- Added a snap-on bottom ring for extra tight fitting of the can and better stability on tables (optional part)
- Added a snap-on top lid to prevent insects from falling in your beverage. It also looks fancy!

I recommend some supports for the handle, the inner part of the lid and the small lever on the lid.
For basic usage you just need to print Dosenhumpenv2.stl. It can be secured on a can, fits in cup holders and can stand upright on a table.
To secure a can in the holder, slide the top part of the can in the top part of the holder (where the handle is attached). Than firmly press the bottom of the can in the bottom bracket and it should snap in.
Removing the can is easiest when the can was emptied but works with a full can aswell: Slightly at the outmost part of the bottom of the holder and pull the can out.
For addional stability when standing, you can print BottomExtension.stl and snap it on the Dosenhumpen. You can remove the extension by pressing the small pins at the bottom and pull the handle out of the extension.
The lid is easily attached by putting the small pin of the lid (the left if you are looking from the top) into the matching hole on the can holder and then press the right pin firmly into the other hole.
You should remove the tap from the cans if you want the lid to "seal" the can evenly.
For left hand use just mirror the lid in your slicer.
