Timelapse/Webcam Phone Holder (with clamp)

So I wanted a simple armed clamp to hold the two surplus iPhone 8's I had; using one for timelapse and one for PrusaConnect seemed a GREAT idea, but initially I had to cobble together things with some phone holders that weren't intended for that task. I honestly thought there would be a ton of those kinds of models on Printables, but was unable to find anything that worked the way I wanted.

The source model for the phone holder end was flexible enough for most phone types, and was clearly based on a highly modified GoPro camera mount. The other end… made zero sense in terms of how it could attach to the Prusa Mk3s it was supposedly designed for, much less the MK4 I wanted it for. You can see my initial workaround of holding it oh with a large clip clamp, but even with the orange handles this was never going to be a good long term solution.

I changed the crossbar arm to use a second wing nut and bracket assembly, and added a bracket to a perfectly sized mini vise from this site. I set the bracket perpendicular and aligned with the vise to give people more flexibility in terms of how to use the armature; when using the “suggested serving” PrusaSlicer file just delete the one you don't want.

I printed mine using .3mm layers, 4 perimeters, 25% rectilinear infill. Sure, you can get away with less, but I wanted a little more rigidity and strength for something I might need to move from time to time and to reduce vibration.

One big change to the mini vise design was the combination of the two screw halves; I was almost certain you could skip trying to align those two things while gluing them together (which seems like a big possible failure point) by standing it up. As long as you use supports, you get a perfect thread every time. Removing the supports from the threads is oddly satisfying (see the pics for an example).

Note: To build this you're going to need:

• 1 Unit: M3 Screw 20mm
• 1 Unit: M3 nut
• 2 Units: M5 Screw 20mm
• 2 Units: M5 nut

The M3 screw and nut works with the phone holder end; you slip the nut in to hold and adjust the clamp. If you size it right, the phone is firmly held, but pops in and out if needed.

The 2 M5 sets are to hold and lock the bracket sections, which are attached to the crossbar arm using the wing nuts. You can put them both on one side or alternate depending on how you want to angle things.
