80MM CNC Vacuum Brush
thingiverse
I swapped out my old spindle for a beefier 2.2KW model that measures 80mm in diameter, and I'm using a 3" flex duct with a custom-made collar boasting an outside diameter of 3". This remake is based on Chemical14's original design, which can be found at https://www.thingiverse.com/thing:4214274. For the magnet design, I drew inspiration from CNCrouterparts' creation - check it out at https://www.thingiverse.com/thing:1363341. To complete my build, I picked up a Vacuum Brush on Amazon (https://www.amazon.com/gp/product/B07VNSD1CJ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1). When it comes to screws, I opted for M8 - 1.25 x 16mm or 20mm Button Head Socket Caps Screws from Amazon, Ebay, or my local hardware store. For the finishing touches, I also grabbed an M8 x 13mm Hex Drive Flat Head Steel Screw Nut on Amazon or Ebay.
