A friend of mine had a big size filament 3D printer, which did not worked well.
He asked me to fix it, so I had the opportunity to use it for my stuff.
Once I got it fixed, I cut the CAD in multiple pieces, and started the prints for the front triangle. Then every parts were bonded together with epoxy.
I machined the pivots inserts on a lathe, and then checked the assembly of these pivots, the rear axle and derailleur hanger, and the BB insert.
To simulate the shock I just used two pieces of plastic tube sliding one in the other set to the correct shock stroke.
I put all these components together and was then ready to check the final result.
January 2017, I was ready to build the bike with all the components.
This step allow to check clearance between the components, which is more than necessary
At this step of the project, I could not stop.
I had some idea to make the bike real, but I am not a composites expert, and I needed to decide the tooling process.
