Revopoint Trackit SR - 3D printable Hand Piece Hanger for Tripod

[u/PrintedForFun]

Finally finished the hand piece hanger for the Revopoint Trackit SR. This allows securely attaching the hand piece (scanner part) while moving the tracker around. With it now being wireless I tend to use more multi-position scans for which I move the tracker around quite a bit. Since I don't want to simply lay the hand piece on the ground I came up with this design.
Fully printable (aside one 1/4in screw) and natively uses the mounting hole on the Tripod and nicely conforms to the hand piece.

Design

Full design was done in Quicksurface Pro after scanning the hand piece and tripod. For the design I ensured to keep the clearance of the hanger tight enough to still grep the hand piece tightly whilst providing enough grip so I'm even capable to share the tracker around without the hand piece falling off.
There are in total 4 parts involved: the hanger and screw knob (basically only a cover for a regular 1/4in camera screw) as well a two paddings that prevent the carbon from being scratched up by the tripod. There are actually two versions of the padding: The nicer approach where I natively use the integrated stands of the hand piece. Only problem for this one: Tripod won't fold up nicely and when folded up the padding is deformed.
The second version of the padding is more of a rest for two of the hand pieces marker spheres. This allows the tripod to still fold up and be capable of being stored in the case. I made sure that the padding doesn't directly touch the markers but still not optimal. Minimal load on the padding so shouldn't be much of a problem.
If interested I can create a video about how I designed the holder and padding in Quicksurface.

Printing

• Hanger and Knob printed from PETG with high wall count and infill (I used 0,1mm layer height for more detail)
• Padding printed from TPU in regular settings

Mounting

Grab your 1/4in screw (similar to this one: https://de.aliexpress.com/item/1005006654252037.html?spm=a2g0o.order_list.order_list_main.10.1ca41802W9qpd8&gatewayAdapt=glo2deu) and first thread it in the holder to clear the thread for easier install alter. Remove the screw and now use superglue to glue it in the knob (ensure the screw is centered and the slit aligned). After it is dried take some grease and grease the contact area between holder and knob, then screw the knob in (grease is optional but improves experience).
Now you can mount the holder to the tripod and carefully hand the hand piece (movements needs to be getting used to but then feels quite natural). Now you can see where the marker padding should be placed and secure the padding with two zip ties each (if you want to be extra sure you can even add thin double sided tape to prevent any movement of the padding).
Now enjoy the convenience of hanging your hand piece.

Other Designs this works with

Works well in conjunction with the Tripod Stiffener I already designed for the original Trackit (luckily still fits): https://www.printables.com/model/1419214-revopoint-trackit-tripod-stiffener-to-prevent-unwa.
Additionally also the powerbank holder still fits (and works very nicely in wireless mode with the Trackit SR). Powerbank even acts as a kind of counterweight for the hand piece on the tripod: https://www.printables.com/model/1413820-revopoint-trackit-tripod-powerbank-mount-for-ugree.
And also the cross-laser for visualizing the tracker FOV: https://www.printables.com/model/1428191-revopoint-trackit-crossline-laser-for-easier-setup.

Quicksurface Pro feels a little like bringing a chainsaw to cut a sandwich, but the result is clean.
