Shenhui Laser Equipment SH-G3020 Air Carrier

thingiverse

Air carrier designed specifically for "aquarium tubing" and intended for mounting on the working end of a CO2 laser engraver/etcher. This air carrier actively blows air onto the working surface to remove any soot/carbon buildup during the etching process. If you're looking for something similar, simply ping me through my thingiverse profile and I'll be more than happy to assist. I printed this design flipped 180 degrees, with the long tube facing upwards. Supports were printed under the bracket and inside the tube, as well as underneath the 45-degree angle section of the tube. Printing the tube itself presented no issues, but I do recommend ensuring you have two or fewer wall layers if using a 0.4 mm nozzle to avoid any problems. Using three or more wall layers resulted in some unusual patterns that didn't print well. For mounting purposes, I used two M3 hex bolts; however, the bracket's holes are actually sized at 5 mm.
