The file 'Wine Glass Holder 3D Printer Model' is (STL) file type, size is 197.9KB.
I remixed the original with better sized holes for the 5mm rods that I find at my local hardware store.
The holes are dimensioned to 6mm as my 5mm wooden dowels for some reason are closer to 6mm than to 5mm.
Additionally, I covered the end so you cannot see the rod from the front.
You need four 3.5mm countersink screws to mount.
