Version 1.2 has 400% bigger filtering area compared to 1.0. It seems to be refined enough to actually use as it now fits under the seat without interfering woth the seat mounting hook. Compared to the 1.1 the shape is a bit different due to the above menetioned clerance issues, but also dueo to maximixing the filtering area size.
The is still room to make the filter bigger, but I feel that it is not necessary. After all, we are dealing with a 300cc single cylinder engine.
The unit itself is glued together once printed. If I can find the time, I will make a version that can be dissassembled. The STL file can be found at the bottom of this post. Use as you please. If you are making money with it, I want a a cut…
