Twist-lock Bike Phone mount (now with Version 2!)

Spare Phone case needed!

The distance between the mounting clamps is 50mm, it fits a handlebar with a diameter of 32mm.

The glue-job does look a little messy, which is thanks to me being a little paranoid about it coming off again, but with some 3M it should be totally fine, I didn't have any so I used a too-optimistic (or pessimistic?) amount of Epoxy glue.

Additional Material needed:

4x  M3x16 or M3x20 screws, doesn't really matter

4x M3 Heat Set Inserts

Phone case

3M double sided tape or Epoxy glue (or something similar)

optional: some padding for mounting clamps (I used some rubber/foam-like piece of a very old mouse pad)

I printed the Mount upside down with some paint-on supports to support the cup, so that the blades would come out as best as possible, but the other way around should also work fine with enough cooling to get decent overhangs. 

The “wart” can also be printed both ways, it all depends on what your printer can do, worst-case there are some supports needed on the blades.

I glued the wart on the case when it was arrested in locked position inside the mount so that I would get the angle right ( I also cleaned and sanded both surfaces). The mount was simply screwed together after inserting the heat set inserts into the clamps.

The angle can be varied until satisfied with viewing-angles while riding the bike. I did add some padding but it is optional and has to be thin or only on a smaller segment.

On my bike the mount has so far lived up without any damage for around 120 kilometers and more than a few potholes, rocks and roots. 

(I am currently working on some improvements, so that the phone can be mounted either vertically or horizontally. I will upload files and maybe pictures as soon as I am happy with the results)

---------------------

Update:

I added a new version, the instructions stay the same, but:

• the clamp is symmetrical now → it needs to be printed twice

• clamp option with place for M3 nut added, so there are no inserts needed (has NOT BEEN TESTED for stability!!!)

• the whole model is a little less chunky

• the “wart” has 3 options for tolerances and is a little smaller now

• No supports on the inside needed, only for under the “cup” and grooves for the handlebar on the mount itself → it has to be printed in the orientation it has on the bike 

• most importantly: The phone can now be mounted either vertically or horizontally!
