I made this model rather large. It almost maxes out my print bed at 210x130x200mm tall. You can scale it to whatever size you like with your slicer. Beware, if you try to print this in the full size with more than 2 perimeters, it will take a LONG time to print (36+ hours) and use a metric ton of filament (>400g). The hexagon walls are obviously at 60deg angles so if your printer can handle that angle without supports then this print will not require any supports at all.
As always, I've included the STEP file if you want to make minor adjustments without trying to modify a terrible STL file. Shoot me a message if you want a different ratio or filled in bottom or whatever and I can try to accommodate.
The author marked this model as their own original creation.
