Smartphone Tripod Mount in ArcaSwiss Monoball Fix Style

Printed in PETG. Used 100% infill for the clip and a 100% infill section for the screw for better rigididy.

This tripod mount requires extra hardware:

• 2× M4×65 screws

• 2× M4 Inserts

• 1× 1/4"-20×12.7 insert (a shorter one can be used too and some height saved!)

You also want to ream (or just drill) the holes for the screws to 4mm. I used a 4H7 reamer - but drilling it to the correct size is probably just fine.

Reason I added the metal parts was bending stiffness. When the clamps are closed, there is a moment, which bends the screw. I had a design with some plastic guides, which immediate snapped off...

The design is a bit clunky and can probably be made way thinner. However, I wanted to have it in the same style as the ArcaSwiss Monoball Fix 32 plate (hence the 32×32mm footprint). Because I only had the 12.7mm height 1/4" insert from CNCKitchen, the bottom had to be that thick...

The knob is actually a bit small. I thought about replacing the 3d printed screw with a M6 threaded rod, add another heat-insert and add a nice Kipp clamping lever... However, then it gets quite bulky. I guess it is just fine as it is... ymmv!

I already sketched the ArcaSwiss mount in CAD but opted to use a proper plate. The FDM printed version does not clamp as nicely as the aluminium ;)

Of course you can model all threads in CAD and also increase the 4mm diamater to have the screws run nicely without reaming to save some time and effort.
