Universal motorcycle phone holder

PLEASE READ THE INSTRUCTIONS BEFORE PRINTING

I was a bit lazy and didn't make it too user friendly (sorry), so you'll need to read the instructions to make it properly.

I created this motorcycle phone holder mainly for function - to be convenient and easy to use above all else. It should fit most handlebars, except for clip-ons and enduro handlebars (the ones with a thinner rod welded above the main tube).

It is designed to be a snug fit - just slide the phone in from above and it'll stay in place. It's also designed to only hold the phone horizontally.

Features:

• Universal (fits most phones - read the Choosing different options chapter below)
• Vibration damping (some parts are made from TPU to damp the vibrations - not sure how effective this is though)
• Sturdy 
• Side hole to allow for charging

Materials:

I used ASA for main components for its strength and UV resistance. You can use some other similar material (like ABS), just don't use PLA.

Some components are made of TPU - these shouldn't be made of any other material, because they were designed to be flexible.

Printer settings:

0.2mm layer height

ASA: 1.6mm wall thickness, 40% honeycomb infill

TPU : 1.2mm wall thickness, 15% infill

Model orientation is probably not correct for most models, so here's the instructions:

• ASA_Main: Print on the side, with supports
• ASA_Side: Print on the largest flat surface, with supports
• TPU_Bot: Print on the side, no supports
• TPU_Mid: Print on the side, no supports
• TPU_Side: Print vertically from the larger surface, with supports

Bill of materials:

• 6x M4x12, countersink
• 2x M4x24
• 8x M4 nut (I suggest nyloc nuts, but normal nuts should work as well)

Choosing between different options:

• The holder is adjustable 15mm in length, which is not enough to accommodate all the phones, so I made three sizes:
  • Small: length 158-154mm, width cca 72mm
  • Medium: length 168-153mm, width cca 77mm
  • Large: length 178-163mm, width cca 82mm
• I made two clamp/main sections, one with a dampening TPU component, and one without:
  • ASA_Main
  • ASA_Main_NO-TPU-MOUNT

Printing instructions:

• Choose the clamp/mid section that suits you
• Choose the size of side parts that suits you
• Print the side parts twice - one as is, and another mirrored 

Testing:

So far it has only been tested on a short ride at speeds of around 130km/h or 80 mph (highway speeds where I live). It held the phone without any issues. The phone was a bit shaky (as expected with the central part being made of TPU), but the image on the phone was visible without any issues.

Do keep in mind that this was tested on Yamaha TDM 900 (touring bike with fairings), so the phone wasn't exposed to any actual wind. It might be different on a naked bike - if someone wants to test this on a bike without fairings, I'd appreciate the feedback.

Final note: 

This model is fully printable and functional, but I'm still running some tests, so I'll update this with more info on usability and add photos of it in use.

Also, you can contact me if there isn't an option that would suit your needs (phone size, handlebar diameter, etc…)
