Cyclonic Dust Collector

thingiverse

Some vacuum cleaners can get overheated if they run continuously for several minutes. This could be hazardous to the machine itself as well as your person or workspace. Be sure to know your vacuum cleaner's limits before utilizing this device. If you want to keep it on throughout the entire machining cycle, consider getting an industrial vacuum cleaner or using a centrifugal compressor sucking nearly clean air from the top part of the cyclone. Keep in mind that efficiency decreases with smaller particle sizes. CYCLONIC DUST COLLECTOR I plan to do some light milling with my CoreXY printer and I don't want sawdust scattered all over my apartment. I learned about cyclonic separators a few years ago during my university days, so I really wanted to try it myself. This one is designed to fit a small bottle of wine, though I can make almost any thread if you give me the diameter(s) and thread pitch. The upper part (outlet) is where the vacuum cleaner sucks air from, and it's meant for a 34x29mm (OD x ID) vacuum cleaner tube. The smaller taper is the inlet, where the cyclone takes sawdust from. The inlet is designed for 19x15mm (OD x ID) PVC hose. I secured the connection with a hose clamp. Once the bottle is full, you can unthread it and dispose of the sawdust. Keep it upright at all times. Alternatively, clamping it to the machine frame would be even better. Consider tipping my channel if you want to keep my projects running. PRINTING TIPS: -Rotate inlet 3º and print it vertically with the outermost part facing down towards the build plate. -Print outlet as is, with a small ring of supports so it fits snugly once the supports are removed. -Cyclone should be printed upside down. You can add supports to the whole where the inlet will be glued (I did just in case). -Use a 0.4mm nozzle and 0.20mm layer thickness (walls are 2mm thick). -Print with at least four top and bottom layers. -Print three perimeters. -Use at least 25% infill. -Glue inlet and cyclone using CA glue. You should get a slight tilt angle (those 3º). Seal the joint with either more CA glue or some polyester or Tamiya putty. -Don't glue the lid to the cyclone; some dirt will accumulate on the inside walls over time, and you'll want to be able to clean it.
