I needed a box for my DIY power bank and because of it size I decided created modular solution to mitigates risks of print fail. Design I come up with was impossible to print without lot of supports, so I was forced to be creative.
Really nice feature of this design, that all side panels printed outer face down on build plate allowing to show up of all nice textures/patterns of build plate sheets.
I would advise against printing box large without adding additional stiffeners for side panels.
I think you can scale it up, if you want more pronounce corners and edges, but I didn't try it myself.
You can adjust outer box size by changing following parameters:
length
- min 60mm;height
- min 60mm;width
- min 60mm.All clearances applied to corner parts, so print one shortest edge, and then print corner base and pit to check clearances. If something too tight or too lose adjust:
corner_edge_clearence
- for adjusting fit between corner base and edge;corner_pin_clearence
- for adjusting fit between corner base and corner pin.You also can model box internals to be able to easily adjust box to your needs like: cutting slots in side panels, adding some structures on internal side to create mounting place adding stiffeners, etc.
Print all parts (except corner base) outside face down on build plate, oriented like example box parts.
I would use at most 0.2mm layer height and 0.5mm line width at least for corner parts, it should help with overhangs.
Print all frame parts:
To assemble frame, slide 3 different edges into corner base and then insert pin corner. Repeat eight times and you will end up with assembled frame:
Then push side panels into their place and put internals if you have some:
I guess frame and or whole box can be glued together, but with all side panels in place it seems sturdy enough.
