Bicycle Multitool 3D model

Bicycle Multitool.
Multitool for troubleshooting.
Can be used in the field.
Stores in the handlebar of the bicycle.
You can use the double bits that are present in the renders (made at random for the demonstration), but single bits I think also can be stored there.
Numerical markings on the front of the multitools: on the left the handlebar standard, on the right the inside diameter of the handlebar near the handlebar grip.
The o-rings are not standard size.
