thingiverse

This is an update log for an OpenSCAD model used to create keyguards for tablets. The updates are from April 22 to November 12, 2018. **UPDATE 11 Nov 2018 (version 12)** * Extended the upper end of the padding options to 100 mm. * Minor corrections to a couple of iPad Air 2 measurements. * Added support for swapping the camera/home button sides. * Added support for sloped sides on outer arcs. **UPDATE 08 Nov 2018 (version 11)** * Added support for iPad 6th Generation, iPad Pro 11-inch, and iPad Pro 12.9 inch 3rd Generation. * Added ability to offset the screen from one side of the case toward the other. * Fixed bug that caused rounded case corners not to appear in portrait mode. * Added ability to create outside corners on hybrid and free-form keyguards. * Added ability to change the width of slide-in and raised tabs and their relative location. **UPDATE 22 Jun 2018 (version 9)** * Combined functionality for both grid-based and free-form keyguards into a single designer. * Added support rounding the corners of the keyguards, when they are placed in a case, to accommodate cases that have rounded corners on their openings. * Can now create cell openings that are rounded-rectangles. * Can limit the borders of a keyguard to the size of the screen for testing layouts. **UPDATE 12 Jun 2018 (version 8)** * Reduced the maximum slide-in tab width from 30 mm to 10 mm. * Added the ability to merge circular cells horizontally and to merge both rectangular and circular cells vertically. **UPDATE 25 May 2018 (version 7)** * Padding options have been moved to the Grid Layout section of the user interface to clarify that these affect only the grid region of the screen. * Changed the width of the right border of the iPad 5th generation tablet to match width of the left border. * Made some variable value changes so that it is easier to see the choices selected in the Thingiverse Customizer. * Changed cover_home_button and cover_camera to display_home_button and display_camera because the original options were confusing. **UPDATE 20 May 2018 (version 6)** * Added support for controlling the slope of top or bottom edges of message and command bars. **UPDATE 08 May 2018 (version 5)** * You can print out a plug for one of the cells in the keyguard by choosing "cell cover" in the Tablet>generate pull-down. * You can add a fudge factor to the height and width of the tablet to accommodate filaments that shrink slightly when printing. * You can add padding around the screen to make the keyguard stronger without affecting the grid and bars to account for cases that go right up to the edge of the screen. **UPDATE 27 Apr 2018 (version 4)** * I've added a new version of the OpenSCAD file - keyguard v4.scad. It provides support for circular cut-outs and puts an option to specify the shape of the cut-outs in the Customizer UI. * At the same time, I've added support for covering one or more cells and support for merging a cell cut-out and the next cell cut-out. **UPDATE 25 Apr 2018 (version 3)** * I've added a new version of the OpenSCAD file - keyguard v3.scad. It has been rewritten to better support portrait mode and to use cuts to create openings to the screen surface rather than defining rails. * This opens the door for openings with other geometries in the future - like circles and ovals. * We fixed a bug in where padding appeared - put it around the grid rather than around the screen. * We increased the depth of Velcro cut-outs to 3 mm, which roughly translates to 2 mm when printed. * The cut for the home button is now made at 90 deg. to not encroach on the grid on tablets with narrow borders. **UPDATE 22 Apr 2018 (version 2)** * I've added a new version of the OpenSCAD file - keyguard v2.scad. It contains all the functionality of the original file and adds support for a new mounting method: "Clip-on Straps".
