Blast Gate 4 inch air duct
thingiverse
This is an inline blast gate for 4" duct , I designed it in multiple parts for easier printing. The blast gate door can be printed or you can use 3mm ply or mdf. I used 6-32 x 3/4" machine screws and nuts but you should be able to use m5's just fine. You will want to print 2 of the BlastGateMain files and 1 spacer and 1 door, or make the door out of something else like previously stated. Print Settings Printer: Da vinci Pro Rafts: No Supports: No Resolution: 0.2 Infill: %20
