ISO838 Based Face Shield Checker

thingiverse

Check that your 3D printed Shield is correctly sized. 1. Print this sheet at 100% scale. 2. Cut along the red dotted line. 3. Fold three times along the dotted line to get a thickness of approximately 0.3mm, similar to the 125-175 micron thickness used by protectourfrontline.org, which falls within a range of 0.25-0.35mm. Paper typically has a thickness of 0.1mm. 4. Fold the edge inward to keep the folds together. 5. Punch using a standard hole punch (6mm diameter hole). 6. Test your print mount point by aligning the strip to each mount point, ensuring it is tight against the frame and creates a seal. The last hole should be difficult to attach as it will snap on. ------------ # Testing DtM-v3 with ISO 838 A4 holes (80 mm apart) Also included is an STL file for testing at prusaprinters.org: mounting DTM-v3 with ISO 838 A4 holes 80 mm apart. Printing a calibration cube may not accurately size the device: * dtm_v3_a4_iso838_Mount_Test.stl: STL file to print and test if your mounting dimensions are correctly sized * dtm_v3_a4_iso838_Mount_Test.mix: Mesh Mixer Source
