Revopoint Trackit SR Cold-Shoe Mount for Smartphone Holders

As already with the original Trackit I designed a mount to use regular cold shoe mounts on the Trackit SR. This allows the use of smartphone holders for live viewing the scan progress. Adding additional weight and strain to the marker sphere may not be ideal and slightly disturb the sphere but I guess it is strong enough to pose no significant risk.

Tried a lot of different options with the Trackit to live-view my scan progress without constantly staring at the PC screen. Started with RDP to my tablet, then RDP to my AR glassed and now landed at the final solution I like the most: I just use a cold-shoe smartphone holder directly at the hand piece so I don't need any special equipment and no additional stuff to carry around. To enable RDP even at offsite locations I have a small tp-link travel router (WR-3002AX) that can be powered over 5V USB, therefore I just plug in LAN and USB to my PC and connect my phone to the WiFI. Et voila RDP works.

Scans

As a base for designing the mount I created a scan of the Tracker hand piece where I tried to cover as much as possible even in the more obstructed areas. I already had scanned the smartphone mount so I didn't need to scan it again. This time there actually was enough space for the mount compared to the original Trackit so I didn't have to pay much attention anyway.

Design

For design I first processed and aligned the scan in Quicksurface. Then I imported the smartphone mount scan and found a fitting position which provided enough contact area so the reversible adhesive tape has enough area for attaching securely. Then imported my reference step model of the cold-shoe, moved it to this place and basically only used one fit surface to extract the curvature of the marker sphere. Thickened the fir surface, sketched an outline I liked and trimmed all the parts into one model (first thickened part and outline). A few chamfers and fillets rounded the whole design up. Whole scan and design took roughly 1/2h.

Printing

Printing is best done from PETG or ABS. Print as I oriented the STL, brim is a must.
You may want to roughen up the surface of the print and use IPA to wipe any grease from the contact areas before attaching the double-sided tape (I used two layers to have a bit of additional thickness). Firmly press the mount in place to ensure good contact. Then enjoy your new freedom from a PC screen with the Trackit SR.

Smartphone Mount used

Any other tiltable cold shoe smartphone mount should also work, just like this one. But this one is tested to ensure buttons are still reachable and has endless swivel points for adjustments. https://www.smallrig.com/de/smallrig-Metal-Phone-Holder-with-Cold-Shoe-Mount-4382.html
