The screw holes in the handlebar mount in the file were too weak and were strengthened. The spring system in the file https://www.thingiverse.com/thing:3466026 was used. 

There are two versions of the lock mechanism, one is the original one and the other is a version made to make it a little stronger, I used both of them, but the second version holds it a little more solidly.

 I recommend you to wash it with PET-G or ABS+. materials you need: 1 piece M3 30 screw 1 piece M3 nut 4 piece M3 10 screw 4 piece M3 nut There are parts that require support but are easy to remove after printing. I use it on my bike now and I am very satisfied.
