Predator_Carb_Spacer_v2_Fixed is 23mm tall
Predator Carb Spacer v3 is 18mm tall
Predator Carb Spacer v6.step is the step file for the 18mm version.
This is a carburetor spacer for a predator 212 that I printed from PolyMaker PolyMax PC. It should withstand at least 230 degrees Fahrenheit. I designed this because the genuine Honda carb I wanted to use had the fuel inlet fitting cocked in such a way that it was impossible to use with the Predator without some kind of spacer(to keep it from hitting the fan shroud). This one is 23mm thick/tall so it brings the carb out far enough to connect the fuel lines normally using the stock hardware and a velocity stack. Measure beforehand and make sure that you'll be able to screw the nuts on the end of your threaded rods, to bolt your velocity stack on. I couldn't find anything like this so hopefully it's useful to someone else besides me. I took the time to line up and port match everything, and I left the mounting holes a little bigger so you can rack it around to get it to fit your specific predator (they're not all perfect)
Yes I realized my pulse pump is routed wrong, and that I put the breather in the worst spot possible on the valve cover. This is my first predator build and I made a few mistakes. (i ordered another valve cover)

Sanding for final surface finish!
Make sure you sand either side of the mounting faces before trying to install this. I used around a 150 grit to roughly take down all the high spots by laying it on a flat metal plate and using a circular motion to evenly sand it down. Then I finished it of with a 2500 grit. I was surprised how smooth it was with just those two grits! It nearly brought it to a polished finish within 3-5 minutes of total sanding!
P.S. If you had trouble getting it to seal, I bet a thin layer of Permatex Ultra-Black would help make a nice hermetic seal! On a flat surface, lay a piece of paper with some Ultra black on it and use a circular buffing motion on it to work it into all the cracks and low spots of the print. Wipe off extra.
