3D Verkstan Face Shield Frame, Pack and Stack, North American Hole Pattern V2, 0.3mm Layer Height

thingiverse

A single stack of 10 parts is printed with a 0.3mm layer height. Three stacks of 10 layout are designed for a 300mm X 300mm bed. The first two files are for the North American V2 version, featuring 6 studs. The second two files are the EU ISO 838 version with 4 studs. Hole punch instructions follow. Note: A 0.3mm gap exists between parts on these models, and print layer height needs to match this setting or slicer behavior will be unpredictable. Printing at a 70mm/s speed with a 0.8mm nozzle and 0.3mm layer height should take approximately 20-25 minutes per frame. NORTH AMERICA This version is designed for use with north american 3-hole "Letter" punches. The original 3-hole pattern proved unstable, so a 1/2" spacer creates a 6-hole pattern with a 1" offset instead. This version should be chosen: When making these in North America and using letter size sheets. To punch the holes: Set your hole punch to the setting for a Letter sheet. Make a test punch in paper and measure how far the holes are from each edge, ensuring symmetry. Print the Spacer piece and place it on top of your guide bar. This is what creates the needed offset. Place the Letter (8.5"x11") and make one punch along one long side, with the short edge resting on the spacer piece. Flip the Letter sheet around its short axis and make one punch on the opposite side, resulting in 6 holes along the same edge. EUROPE This version is designed for use with the ISO 838 2-hole punches common throughout Europe. This is the recommended version: When making these anywhere in Europe except Sweden. To punch the holes: Set your hole punch to the setting for a A6 sheet by pulling out the guide bar until it says "A6." Make a test punch in paper and measure how far the holes are from each edge, ensuring symmetry. Make one punch on one side of the long side of the A4 sheet. Flip the A4 sheet around its short axis and make one punch on the opposite side, resulting in 4 holes along the same edge.
