Wall Mount Guitar Holder v2

a tame cat appeared in my house, which means that I had to remove musical instruments from the floor, I had 2 factory hangers for guitars, I thought to print two more according to the model I indicated, but there were problems with its location in the slicer.
I remade this model, firstly, now it is printed in a horizontal plane, which means that the print fibers will hold it more firmly, which means that you can save plastic and print with a lower percentage of infill, and secondly, I made recesses for standard 6mm dowels in concrete walls with a hat, which are widespread in Eastern Europe.
