I’m working on a replacement for a broken shelf in my fridge door. It’s about 37.6 cm (14.8") on the longest axis so I need to print it in two pieces (as shown in the screenshot). Does anyhone have a good idea for a connection between the two that will be sturdy enough? The fridge door will support it from below for about half of its depth, the rest hangs free.
Wall thickness is currently at 3mm but I can increase it a bit if needed.
I’d thicken the bottom, and then have the interface have some pegs/holes to fit together like a puzzle. If you’re printing in that orientation the pegs should be unlikely to shear off. Then, lots of super glue and sand it down. As others have said, a lip underneath the interface would give you more surface for super glue as well.
Because it’s going in your fridge, there will be inevitable spills that need cleaning. So I’d want to minimize the seam and complexity on the interior of the container.
