These are leftovers from items I made for myself using a 3D printer. I can create more, so please contact me if you'd like. They are made of ABS resin and have some heat shrinkage, but in my experience, it hasn't been a problem. They cannot be used on 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 details. I will create a dedicated page for you, so please do not purchase from here.
