Foamboard block corners and ends for 5mm board

thingiverse

Frustrated with crafting crumpled corners on foam card buildings, I decided it's time for a change and create smooth ones instead. Additionally, doorways and ends need to be designed to match perfectly. Some corners are reinforced for extra security. The blocks measure 96mm in height, making them compatible with most printers and allowing them to stack neatly on top of each other. To add variety, you can mirror the opposite corner or flip it upside down. The block ratio is proportionate, so stacking is preferred over stretching, but if you do choose to stretch, be sure not to exceed 128mm in height.
