Marcy NS-652 Exercise Bike Adjustable seat handle

I lost the seat adjustment for one of my Marcy NS-652 folding bikes. I could have maybe called them up to have them ship me one but I though it might be easy to 3d print with the help of a m6x60 bolt from the hardware store. Its held up pretty well so far.

I designed a 1 layer false floor for the overhang where the bolt enters, just poke it out with a tweezers.

Print at 0.2mm with at least 4 perimeters. 25% infill or more.
