Check that your 3D printed
Shield is correctly sized

1. Print this sheet at 100% scale.

2. Cut along red dotted line

3. Fold 3 times along
   dotted line to get ~0.3mm
   thickness. This is similar
   to the 125 to 175 micron
   thickness of the shield that
   https://protectourfrontline.org/
   is using. This is between
   0.25 to 0.35mm thick.
   Paper is typically 0.1mm

4. Fold edge inward to hold
   the folds together

5. Punch using a standard
   hole punch (6mm dia hole).

6. Test your print
   mount point by aligning
   the strip to each mount
   point.
   Should be tight against the
   frame so it creates
   a seal.
   Last hole should be hard to
   attach as it should snap on.

Testing DtM-v3 with ISO 838 A4 holes (80 mm apart)

Also included is an stl for testing https://www.prusaprinters.org/prints/28905-dtm-v3-with-iso-838-a4-holes-80-mm-apart/files mounting. Printing calibration cube may not size the device correctly:

• dtm_v3_a4_iso838_Mount_Test.stl : STL file to print so you can test if you got your mounting dimentions correctly sized
• dtm_v3_a4_iso838_Mount_Test.mix : Mesh Mixer Source
