Vacuum Sucker for bell saw (Customizable in FreeCad)

thingiverse

I highly recommend the exceptional Vacuum Sucker for Drilling by jonnieZG, which is essentially a modified sucker designed specifically for bell saws. The accompanying STL files are available for download and include two separate designs: a 65mm diameter bell saw with a 70mm hole diameter, as well as a 35mm vacuum tube compatible with Karcher models. One of the standout features of this tool is its customizability through FreeCad software. Users can easily modify parameters by adjusting settings in the "Params" spreadsheet, allowing for seamless customization to suit individual needs. It's worth noting that this design was created with personal use in mind; however, if you plan to utilize it professionally, I would suggest reinforcing the parts by increasing their thickness to ensure durability and performance.
