Dashcam Rear-view Mirror Mount

Overview

This dashcam rear-view mirror mount is designed so that the dashcam never falls down again. Usually, dashcams come with a suction cap mount for the windshield and these like to fall down on warm days, hitting dumps or just after a few days as the suction wears off. To stop this from ever happening again, mounting it to the rear-view mirror is the answer. It currently only has an attachment for the Navman camera mount, however, you can redesign the part to fit the mount of other dashcams (Fusion360 file attached, feel free to remix).

I only recommend using ASA for this part as it will need to endure UV and heat. You can use other filaments like PETG or Polycarbonate, but other than that, I don't suggest using anything else.

Parts and Materials

1. 3x M4 30mm bolts
2. 3x M4 washers
3. 3x M4 6mm heat thread inserts
4. ASA filament
5. Self adhesive felt guard (50mm x 15mm)

Printing

I have provided the 3D files as well as a gcode for the Prusa MK4. If you need to make any adjustments to the part, there is also the Fusion360 file. When it comes to printing, in your slicer remove all support on parts other than the “Mirror Mount (bottom)” and “Dashcam Attachment”, leaving support only on the spherical attachment points ONLY (screenshots provided to show this).

Settings to Adjust in Slicer
• Strength: Set "Sparse infill density" to “60%”
• Enable support and leave all else as default
• Set “Brim type” to “No-brim” (unless you really need it)
 

Assembly

All is shown in the images provided

1. Insert two “M4 6mm heat thread inserts” into the part “Mirror Mount (top)” from the top of the part. 
2. Insert one “M4 6mm heat thread insert" into only one of the “Middle Connection” parts from the outside (not the face of the part that will touch the other part).
3. Cut “Self adhesive felt guard” to size (if needed) and apply to curved inside of parts “Mirror Mount (top)” and “Mirror Mount (bottom)”. 
4. Add the washers to your bolts
5. Insert one of the the “M4 30mm bolts” through the “Middle Connection” that doesn't have the heat thread insert and into the one that has the heat thread insert. Only screw the bolt in slightly (keep it loose).
6. Insert the parts “Dashcam Attachment” and “Mirror Mount (bottom)” into the middle assembly and tighten the bolt to be as tight as possible. Minimal movement of this assembly is optimal, but slight movement may still be present which is normal.
7. Slightly screw one of the last remaining bolts into “Mirror Mount (bottom)” and loosely attach “Mirror Mount (top)”. Do not screw the last bolt in on the other side, do this when attaching to your rear-view mirror.
8. Slide the assembly over the arm of your rear-view mirror and insert the final bolt to complete the assembly. Make absolute sure that both of these bolts are tightened equally and also make sure that the assembly does not move on your rear-view mirror. Also be mindful to not damage anything in the process.
9. Dashcam should slide onto the mount with some force applied and shouldn't slide off easily. If it slides off, adjust the tolerance by scaling part very slightly in your Slicer or in your CAD software.

Conclusion

I hope this dashcam rear-view mirror mount works well for you, I spent a while designing and testing it for my dashcam and rearview mirror while making sure that it can be universal. The only part that you will need to redesign for other dashcams is the “Dashcam Attachment”.
