My Ryobi Band saw has a large hole for a vacuum cleanout, however it did not fit my shop vac. I designed the vacuum adapter.stl to adapt my shop vac to the band saw.  It will fit most 1 1/4" vac hoses.  Also the throat plate that was provided with the band saw was improperly made and was not flush with the table and had an overly large slot around the blade. The throat Plate.stl cured the problem.  I printed these in PLA at 200u with 4 perimeters 4 top and bottom layers with a 20% Triangle infill.
