Workbench Dowel Paper Roll Holder

Having a roll of paper for my workbench to keep the mess to a minimum has been very handy in my workshop. My previous holding solution (plywood holder) worked okay but busted when a heavy clamp hit it. So my paper roll sat on the floor as a trip hazard for a while till I came up with this idea as my new solution. I designed the mount to use a sliding dovetail joint for ease of lifting out the dowel (¾" diameter) with and without the paper roll on it but still leaving it a tight fit. Just mount the two mount plates on your workbench or whatever surface, measure the distance between the two mount plates and add 1 ½ inches to it for the mount hole depths. I printed mine with 20% infill and 4 walls. The brackets had to have supports enabled in the orientation I printed them (and if I did the print file right they should be orientated in that position with supports enabled). Still new at 3D print designing so if you have suggestions or constructive comments feel free to share.
