Evaluation of members on the printability, utility, level of detail, etc.


3D model description

I designed this to save a couple dollars and learn more about engine building! Design requires 2 8x22x7 bearings and fasteners for the clamp on the right.

What is it?
A 3d print affordable split weight jig so you can balance your big and small ends for engines with more than one rod. Areas to remove material and symmetric weight removal is beyond the scope of this tutorial.

Notice: this is a work in progress, tolerances will need work or possible work to accomedate bearing gaps. Print at your own risk but please, do provide critique for improvement. Topo schtuff to be included later.
