Made a basic parametric cooler to have fresh drinks after a bike ride, back at the car.
The lid automaticall locks when carrying the box, or when the handle is in the back. Rotate the handle to the front and Sesame opens.
Can be sized to match different can and bottle types and to hold as many as needed, starting at 2x1.
Several versions were generated, so either pick the one needed, or generate a custom one via Fusion360's parameters:
The Fusion360 CAD model, STEP and 3MF files are on Github and MakerWorld
Feel free to copy, remix, whatever (non-commercially)
Fresh picnic drinks for all !
Settings
- Any filament material
- 1.05 flow (overextrusion, very important for waterproofing)
- 3 walls, 6 top, 4 bottom
- Seam in the back (scarf or not, makes little difference)
- 15% Adaptive Cubic infill
- Normal Auto support only for the handle, none for the rest
- if the bottom perimeter chamfers on the box and the lid print poorly with wavy / droopy appearance, set a 24mm (box) and a 10mm (lid) height range modifier with 50mm/s speed for both Outer and Inner walls
Finally, to install the handle just give it a good whack on each side, to push each pivot into the box.

Key parameters to customize the cooler:
Changing the box size is usually best done by changing dimensions in the following order: inside_length, inside width, inside_height.
handle_height should automatically update when inside_width changes.
wall_thickness applies to the whole box and the lid. Increase it for more insulation.
The dimensions for a number of beverage containers are already included in the list of parameters:
So to upgrade the model to, say, 6 Pepsi plastic bottles, update the cooler dimensions to a 3x2 setup as follows:
Can even size it to hold a couple of 2015 Les Voleyses Crozes-Hermitaze bottles. Le rêve...
Also, fun stuff: playing with filament colors can be done in Fusion360 thanks to the PrintBusters script. It provides some filament colors from Prusa, Bambu and Polymaker as material appearance:
