Dust shoe for RS-CNC32
Description
PDFThis dust shoe builds on the ideas of:
Those two are in turn based on the ideas of:
Routers (and I imagine any air-cooled spindle) produce a strong downward airflow. The purpose of the upper chamber in these designs is to redirect the airflow sideways, so that it doesn't interfere with dust collection in the lower chamber.
The earlier designs have a small vacuum opening of about 5 cm² at the far end, which restricts airflow considerably. By increasing the opening through widening and raising the height of the lower chamber, this dust shoe is able to move more air. The vacuum adapter connects directly to a Ø50 mm hose.
The lower attachment connects to the dust shoe with magnets. It comes in brush and skirt variants.
- Brush Attachments.3mf have a wide groove in which bristles can glued in. A good process of making a bristled brush can be found in these videos:
- Skirt Attachments.3mf have a thinner groove in which a skirt fits. The model for the skirt itself is 1 mm thick and will need to be cut in the slicer to a suitable thickness. That thickness depends on the stiffness of the used filament. I've had good luck with 0.30-0.40 mm with PETG (and will be trying TPU soon).
Required hardware:
- Aluminum mounting bracket for Ø65 mm router (aliexpress).
- 4 x M6x80-90 socket head bolts. This depends on the thickness of your Z-axis plate and M6 nuts (i.e. Nylocs are thicker) .
- 1 x M5x30, 1 x M5x40 bolts, 2 x M5 nuts.
- 16 x 6x3 mm magnets.
Print settings:
- The 3MF file contains support enforcers for Prusa Slicer. Otherwise, use paint-on-supports as shown in the screenshot.
- I've printed it successfully with PLA, PVB and PETG, 0.4 mm layer heights and a 0.6 mm nozzle. Anything should work.
