Canyon Grail SP Connect Smartphone Mount
Here is another update (V6) of the original holder. I added a stronger and rounded connection of the middle arm to reduce stress peaks (middle arm broke on a tough ride in V5) and also widened the arms a little for even more stability and less virbration.
I left in V2 (2 arms) and V5 (3 arms) in case you want something just for a bike computer on the road, but when it gets a little rough I strongly recommend V6.
This is a Phone Mount for Canyon Grail bikes for SP Connect mounting.
The mount is made for SP Connect Head SPC+ Moto Pro (MTB) - see link below.
I also added an adapter for SIGMA ROX or GARMIN Bike computers to the AERO Stem Mount - see link below.
The Screw to connect the SP Connect Head is the screw that comes with it. On the other site I used an M5 standard nut.
The screws to mount it to the bike are M4 countersunk head screws.
I printed it PETG. For more stability I can also recommend to use SLS Printing (or SLM if you want it in metal).
As inspiration for the base I used a model created by Michal Nemec for Garmin, found on GrabCAD:

Using some dimensions out of that I built the part in Solidworks and printed it on a BambuLab X1C.
