Parametric Enclosure Frame

prusaprinters

The attached OpenSCAD code will generate pieces to build the frame for an enclosure. The main parameters are:width - interior width (X dimension) of frame depth - interior depth (Y dimension) of frame height - interior height (Z dimension) of frame strutWidth - cross-sectional width of strutprintWidth - width of your printer's print areaprintDepth - width of your printer's print areaThe SCAD code will calculate the maximum length of strut (edge of the enclosure) that can be printed diagonally on your printer, and divide the required length into segments that will fit. It also rotates the segment so that it will fit diagonally on your print bed.Typically, for an enclosure for your printer, the struts will be cut in half, requiring you to print 8 of each and join pairs of them using the pegs.The code prints out stats on the enclosure frame that look something like this:ECHO: “Strut rotation: 49.8566”ECHO: “Max strut length: 317.731”ECHO: “Number of corners: 8”ECHO: “Number of 250mm X struts: 8”ECHO: “Number of 272mm Y struts: 8”ECHO: “Number of 300mm Z struts: 8”ECHO: “Number of pegs: 12”ECHO: "Outer dimensions: 516x560x616mm"So, you'd need to print 8 of each type of strut, 12 pegs and 8 corners. You'd then assemble the pieces as follows:Join pairs of strut pieces using a peg for each pair. (This results in 12 struts: 4 for each dimension)Assemble the frame by joining the 12 struts using the 8 corners.I've included the STL files for a 500x544x600mm enclosure. This is just barely enough room for a Prusa Mk3 with a spool holder. There are files for one using 8mm wide pieces and one using 12mm wide pieces.What you use for panels is up to you. For example, you could cut acrylic panels to fit. NOTE: the “Outer dimensions” line of the printout above dictates the dimensions of the panels required.
