Originally, I made this as a one off to keep tissue boxes off the bathroom counter tops so they don't get wet when the water splashes, but I have modified the model to be parametric so it can be used for other items.
The bits go together with dovetails. They fit pretty tight from my printer. There is a “Clearance” parameter (set to .25mm) in the model to make the fit tighter or looser. Here are the other parameters.
ObjectLenght (sp) and ObjectWidth are the based dimensions of the supported object. Thickness sets the thickness of the beams, runners and legs. The WallThickness sets is the thickness of the perimeter wall at the top of the stand. You can probably change the WallHeight (sp) parameter to a numeric value. Be careful about changing any other formula-based parameters.
You can print the beams and runners with the bottom layer set to zero (0) to save some filament and cut down on potential warpage.
I generally print this with PLA but will be trying some with Flex for the legs in the near future.
You need to print 4 Legs, 2 Beams and 2 Runners for a set.
I have variations of these stands (i.e. no walls and legs that are cross pieces and tees) that I am going to parameterize for my own use in the future. If there is interest I can post them as well.
The author marked this model as their own original creation.
