Spacer to fit a PZ16 carburetor on a NSR50

I'm on and off tinkering on my NSR50 project bike. I want it to be as stock as possible, but original carburetors are surprisingly hard to come by (or ridiculously expensive), so as a temporary solution I designed this custom spacer to allow a super cheap PZ16 carb (same inner diameter as the original one - 16mm) from AliExpress* to be mounted to the original intake manifold.

The bore of the PZ16 is slightly offset to the hole in the original intake manifold; this spacer balances this out.

Notes:

• The part fits, but I have not yet tested it! So …

• … I don't know if it will hold up. I printed it in PETG and hope that the water cooling carries away enough of the engines heat. We'll see if this works.

• The quality of mine is actually really nice!
