4" slide gate valve

thingiverse

I'm building a slide gate valve to shut off my printer cabinet exhaust when it's not in use. The valve requires 4mm bolts that are 16mm long; no additional support is needed, but you'll need to position the parts correctly. I've successfully printed the design and it functions well (photos attached). It's a medium-duty piece of equipment. If someone expresses interest, I could create a heavier-duty version, but the current design takes over 10 hours to print. A more robust version with a 5mm thick body would take around 15 hours or more to print. V5 updates increase the flange wall thickness by 1mm; if you encounter issues where it's too tight or loose, simply reprint the spacers, not the other parts, as they take much longer to print.
