Depstech DS529T boroscope Magnetic Bracket

I use the Depstech DS529 to inspect and work on the internal areas of machinery. I needed to be able to mount the camera display and free-up both hands to guild the camera end of the optical cable as well as work on specific parts with both hands when required.

I designed a bracket to hold two bar magnets and experimented with the magnetic gap to dial the holding force in for fixing the display on the machine so it would not move while I used the camera end. The magnetic gap that worked the best was 0.5mm; the attached design reflects that design parameter using the bar magnet assemblies listed below.

Purchased parts from Amazon.com:

• Magnet-pro Rectangular Magnets 70 LB Force Size 2.36" x 0.53" x 0.20" with Counterparts and Countersunk Hole, Household and Industrial Pot Magnet with Screws - Pack of 6. This kit comes with the fasteners to attach the magnetic return path assembly to the printed part.
• 3M VHB [~1mm thick] tape that I used to fasten bracket  assembly to Depstech endoscope display body worked great.

Setup used for printing the bracket:

• Prusa Mini + Printer
• Prusament PETG filament 
• 0.4 nozzle; 3 perimeters; 30% gyroid fill
• no supports were required
• Print mode 0.15 Quality; only used this to get the definition in the lettering but not a necessity. My 1st prototype I used the Prusa Slicer Input Shaper mode for a quicker print for trying out some design ideas
• The overall height of the design was chosen so the high end protrusion on the Depstech case was pretty much level with the top of the magnet bracket assembly, this allowed it to sit flat to the surface it was attached too.
