This is an updated version of the phone holder i made last year, i decided to make it a separate model because it has tighter tolerances and is not fully compatible with the V1. 

Please, share your feedback if you like this model.

New in V2: 

Less material usage, higher durability, stronger grip, better handlebar stem clearance, support for bigger phones, a general visual redesign. All V1 remixes are compatible with V2.

Fully 3D printable (No screws, glue, etc.), 

Center mounting,

Horizontal orientation,

Access to all ports and buttons,

Strong grip on both the phone and the handlebar,

Support-free printing.
 

Designed to fit standard 31.8mm (1.25") diameter MTB handlebars, 25.4mm (1") spacer included in the archive. For 22mm, check out the remix by moWerk, and Shaun577's remix for 35mm handlebars.

Can hold 65-85mm wide and up to 10mm thick phones. (Pretty much all phone models are in this range).

Easy to print/assemble/use, no supports/rafts/brims are required, no bridges or extreme overhangs.

Pay attention to your handlebar stem sizes. In my case there's plenty of room, but it might be too thick to fit on some bikes.

Print settings:

PetG is recommended for better toughness and impact resistance.

Layer height of .12mm is optimal, increasing it will negatively affect parts fitting.

3+ Wall loops.

Enable “Precise wall”, “Arc Fitting” and “Aligned Seam”, if available in your slicer.

Do not use supports, rafts or brims.

The “All in One” model fits on a 15x15cm bed.

Check the archive for individual STLs.
