Clamp - Universal motorcycle phone holder

Since all the phone holders I found online were either expensive or just bad, I decided to make my own.

Note: This was designed for metric standard elements and 23mm handlebar diameter. Contact me if you want me to redesign it for different needs.

Also, The clamp was made slightly bigger to allow for some rubber to be placed between the handlebar ant the plastic clamp, so it doesn't damage the handlebar.

Features:

• Universal (fits most phones)
• Adjustable (sphere in the mid section allows you to rotate the phone and adjust the angles)
• Vibration damping (some parts are made from TPU to damp the vibrations - not sure how effective this is though)
•  Sturdy 

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.

Three 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, no supports

TPU Mid section: 1.2mm wall thickness, 100% infill, no supports

TPU Clamp: 1.2mm wall thickness, 15% infill, auto supports

Model orientation is correct on all models except for ASA_MainSection.stl - this part should be printed on its side. Pay attention to the screw/guide holes, they have a chamfer on one side which should be pointing upwards.

ASA_HandlebarClamp.stl can be printed as is or on its side - up to you to decide.

Bill of materials:

• 1x M6x60mm hex bolt
• 1x M6x30mm hex bolt
• 2x M6x30mm allen key bolt with cylindrical head
• 3x M6 nut
• 1x M6 nyloc nut
• 1x M6 long nut (18mm)
• 1x M3x40 bolt with countersink head
• 1x M3 nyloc nut
• 4x 2.2x10mm screws
• 2x 6mm aluminium/steel rod, 70-80mm long

Assembly:

1. Insert the 4 screws in the mid TPU section and screw the part on the main ASA section. Then, insert the M3 bolt and M3 nyloc nut and tighten it (not too much though). If the nyloc nut doesn't tighten (keeps on turning), use a small screwdriver to keep it in place.
2. Insert the M6x60 bolt in the screw holder, then insert the assembly into the top section so, that the screw holder is on its flat surface. Then, insert the 6mm rods into the holes. The fit is designed to be very tight, so I suggest using a hammer. Lastly, screw the M6 nyloc nut on the bolt to the very top until it's almost tight, but it still needs to be able to move freely.
3. Insert the M6 long nut in its hole, then insert the top section assembly on the main section.
4. Insert the ASA main section on the TPU main section. Then, insert all the fasteners as shown on the photo.
5. Insert the two TPU holders on the top and main section. The fit is designed to be very tight, so it doesn't fall off on its own when not in use.
6. That's it, you're done!

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 me 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.
