Thank you to Bryan Jackson, MS, DABR for his inspiration in 2018 to start this project. Designed to be printed on a standard RepRap style 21x21x25 cm build volume printer. Modular design to suit desired use. Most commonly used screw holes highlighted for convenience. Suggested infill: <ul> <li>Holder: 15% (to save time)</li> <li>Sliders: >= 20%</li> <li>Screws: 100%</li> </ul> Angled support "flanges" are designed in the holder STL file to minimize bed supports and print time. Remove the support "flanges" once printing completed. Use your slicer settings to utilize support enforcers to just support the "flanges" instead of starting all the way from the print bed. An internal brim is design in the holder STL file to maximize bed adhesion. Slicer brim would otherwise extend outside of the build volume. Remove the brim once printing completed. The slider is designed to allow maximizing frame placement anteriorly/posteriorly for hard to reach targets. It employs a "dovetail" design. STL files are saved in print orientation. Suggested parts / quantities to print: <ul> <li>Holder – qty 1</li> <li>Slider (35 mm extension) – qty 1</li> <li>40 mm screw – qty 4</li> <li>60 mm screw – qty 2</li> <li>80 mm screw – qty 1</li> <li>Flat screw tip – qty 5</li> <li>30 degree screw tip – qty 2</li> </ul> Mannequin head model adapted from: https://www.thingiverse.com/thing:4565947 Knurled surface finishing library used: http://www.thingiverse.com/thing:9095 Screw library used: http://www.thingiverse.com/thing:8796
