shape of opening, rounded rectangle corner radius – all rectangular openings will be rounded rectangles and the minimum corner radius of each rounded rectangle is determined by the size of the rectangle,.horizontal rail width, vertical rail width – horizontal and vertical rails have to be at least 3 mm wide for smaller tablets and at least 4 mm for larger tablets,.case opening corner radius – the case opening corner radius has to be at least 2 mm (an exception is made when you add custom case additions),.mounting method – only “No Mount” and “Slide-in Tabs” are supported,.bar-edge slope, rail slope – all slopes will be 90 degrees,.preferred rail height, free-form keyguard thickness – your final design will be 3 mm thick… what the laser-cutter actually uses is a 2D representation of your keyguard (think of it as the bottom layer of the print) so the limit of 3 mm is just for visualization,.keyguard.scad supports the Keyguard AT recommendations in two ways.įirst, you may find that the Customizer pane ignores or limits the choices you make for the following options: Keyguard AT will even cut your design for you (more on that below). They had some specific recommendations for the thickness of the rails and the shape of the openings.
We turned to the folks at Keyguard AT for their recommendations regarding the design of a laser-cut keyguard. Definitely come back here and read through the page thoroughly when you’re done with your design. You may also want to skim the instructions below as you step through the process. That way the image displayed for you will always look like a laser-cut keyguard.
When you are told to choose a “type of keyguard”, choose “Laser-Cut”. Keep this tab open in your browser as you step through the instructions for designing a keyguard.
As a result, you may find the edges of the openings and the edges around the outside of the keyguard are too sharp. A laser-cutter only cuts the acrylic sheet at a 90 degree angle, so there’s no way to angle the opening down into a cell.Laser-Cutting Isn’t 3D-Printingĭesigning a keyguard for laser-cutting is very similar to designing one for 3D-printing, but there are a few limitations.
#Openscad export svg download
But don’t do that, download OpenSCAD and follow the instructions below. Well, you “can” do it, but it will require you to use something like TinkerCAD to import your STL file, then reduce your design to a single layer, and finally export the result as an SVG file…. Note that you CANNOT create a keyguard design for a laser-cut keyguard using the Thingiverse Customizer because it can only create STL files.
