Perfect for those little upright casters. Scale to fit your needs. NOT RECOMMENDED FOR GRAND PIANOS. I'd recommend printing at 100% infill, but you could probably get away with about 60%, depending on how heavy your piano is. If you have any complaints, just whine about it in the comments, and I'll do my best to fix it. I might need to thicken up the bottom a little bit. Print and share and let me know what you think. I love feedback
