These are extra items I made for myself using a 3D printer. I can make more, so please contact me if you'd like additional ones. They are made of ABS resin and have some heat shrinkage, but in my experience, it hasn't been a problem. They are not suitable for walls or ceilings. Please use them on the floor. These are handmade items, so please understand. Please refrain from purchasing if you are overly concerned about minor imperfections. I will create a dedicated page for your order, so please do not purchase from here.
