We have a heavy bed and needed to move it in order to paint behind it. Using these movers I was able lift each corner of the bed and place 1 mover under the post so that it could be slid around with no damage to our carpet.

These were created in Tinkercad. They are 40mm tall. The square hole is 62mm by 62mm, and is 20 mm deep. I used Bambu's 0.20mm Strength Profile.
