Adjustable Spool Mount for 4mm Aluminum or Box Frame

SummaryWhen my old filament spool mount snapped I opted to design a new filament spool mount for my printers: a Prusa i3 Box Frame and an Aluminum Frame. This mount was made to screw/bolt into a solid plate. This works well for the box frame, but with the aluminum mount you'll need to install a plate to the top of the frame (or somewhere nearby). The .scad files I have included are a mix of parametric and nonparametric. The Adj Spool Mount file is parametric and you can change the variables within it to set bar thickness, wall thickness, height, number of holes for extension purposes, screw sizes, etc etc etc. The aluminum frame mount is using an M5 threaded rod and the box frame mount is using an M8 smooth rod. Also included is a variable for printer error. This is my first design with this included and I think I may include it in later files as well. This variable allows for the design to have a printer-error-gap everywhere two parts are supposed to be close to one another. Setting the error value to 1 creates a 1mm gap between these parts. Fiddle with the value and you'll see exactly what it is doing. Comments are welcome.
