This is primarily a shoe rack utilizing a steel or wooden rod (8 mm default), which floats in 20 - 30 cm above the floor. So you clean the floor underneath it and the rack design is better than just putting a rag on the floor. At least it should not be offensive to anyone. ;-) Please let me know if you need help.You can print holders in different configurations: Short rod -> left.stl and right.stl (or 2x center.stl) Long rod -> left.stl, at least one center.stl and right.stl (or you can just have 3 or more center.stl) I printed this in 0.4 - 0.2 mm layers with 8 mm diameter 900 mm long rod and it works pretty fine. My configuration is left, center, center, right. Choose flat screw type if you want o hole for the screw diameter only, otherwise the hole for a recessed screw is made. Please use 30 % infill or even more for better strength. Default customized setting are fine for most (even small) shoes.
