I needed a foot stool for playing classical guitar, but I wasn't able to buy one right away. I also didn't want to spend 10+ hours printing one out. This printed foot stool combines with a cardboard box to give it height without the long print time.

I chose this size box because that is the kind of box my prescriptions come in every month, so I would have replacement boxes if I messed one up. The measurements of the box are 16cm Long by 10.2cm Wide by 16cm tall.

I printed this model in PLA with a 0.20 layer height and 15% gyroid infill. I placed it with the flat part facing down, and no need for supports. Took almost 6 hours to print (but that's less than  10!).
