The 1x1x1 building block is a 3 inch by 3 inch by 3 inch (76mm by 76mm by 76mm) cube intended to be used as a fill in size for commonly found cardboard building blocks.
This is meant to be a child's toy to help further bolster creative play.
The block is hollow to keep weight down while still being structurally sound. Large corner radii have been applied everywhere to maintain part safety as much as possible. The part should be printable without any supports needed.

Thank you to everyone who has downloaded, made, rated, commented, and added this model to collections. I'm getting back into making designs of things I enjoy and find useful, and I'm setting up a Ko-Fi account as a way for people to send a financial tip or thank you, only if you feel led.
If you do leave a tip, please share which model you came over from and what you enjoyed about it!
