CNC Spindle Brush

thingiverse

I'm finally starting to operate my homemade CNC machine. Given the significant amount of dust and debris it produces, I decided to build a brush holder to collect dust and debris and connect my vacuum to the machine. Essentially, there are two dovetail rails mounted on my Z-axis, with two brackets that slide in. The brush slide slides into these two brackets, then is held by two spring blockers. The complex brackets/slide can slide up/down along the Z-axis; once it reaches the desired height, the system is secured in position using two M5 bolts. The brush slide has an opening on its back side to allow the CNC mill to slip inside. The square opening fits Kress's chuck perfectly. I printed the parts without considering strength rules (i.e., the dovetail rails should be printed vertically – I printed them horizontally – for added rigidity), but the device doesn't require such strength, so hopefully, no problems will arise. To complete this project, you'll need to print two pieces of slide and clip. Required materials include: - M4-M5 bolts and nuts (2 M4 & 2 M5 – self-blocking) - Small wood screws - Two small springs (used in ball pens) - Two wooden plugs, 6 mm - Two pins (small nails can work fine) - "The brush" Regarding the brush: I used an excluder brush for doors and windows with its own rail. The rail is cut and epoxy-glued into the main slide. This allows me to easily mount a new brush or interchange different sizes. Please note that this system fits my homemade CNC Z-axis dimensions, making it not a universal brush slide. For the sake of honesty, I got the idea from viewing this video on YouTube: youtube.com/watch?v=ufXtl2VmME
