The file 'Carburetor Airbox (air Filter Holder) For Motorized Bicycle – Velocity Stack 3D Printer Model' is (stl) file type, size is 395.5KB.
AFTER MORE THOROUGH TESTING, I RECOMMEND NOT TO USE THIS ONE. Airflow is not good after my engine warms up. Use my other one if you want one that works without needle adjustments. THIS ONE WORKS ON MY ENGINE FINE: https://www.thingiverse.com/thing:3582289
This is really just an add-on, you will also need to print Carburetor filter conversion for motorized bicycle by OkurRo for this to work.
If you want a simple version, check out my other remix that is all one part and just has a simple hole. https://www.thingiverse.com/thing:3582289
But if you are a geek like me, add a VELOCITY STACK! Good news! The velocity stack adds 200HP! LOL Ok, I know it is relatively pointless, but why not?!?
I did this using OpenSCAD. I would publish it as a customizer, but it has some dependent libraries. OpenSCAD content is posted below if you are interested.
So for now I've published 2 STL files - one tiny to fit small frames like mine (14mm high and 45mm bell - CarbFilterConversion-Velocity_Stack-pub14hx45bell.stl), and one relatively larger for normal size spaces that is 28mm high and a 55mm bell.
If anyone wants a different size, drop a comment or a message and tell me the height and bell dimensions you want (mm).
