Half Inch Conduit Wall Holder

My mother has a painted sheet that was previously stapled to a wall and needs to be changed, the sheet has a slot where a rod fits easily,So I came up with the idea to use ½ inch metal conduit to hold it straight on the wall. These holders are designed so the pipe won't fall down easily even if the fit is a bit loose. NOTE: The conduit I used has 18mm outer diameter, so the holder has an inner diameter of 18.5mm, making the fit a bit loose. I include the fusion files in case anyone needs to modify the design and make it fit their own needs.
