Vacuum adapter for Stepcraft HF500

thingiverse

This is a 3D printable replacement for the Stepcraft vacuum adapter for the HF500 spindle. I was having clogging issues with the original one when cutting MDF, so I redesigned it to make the internal tubes wider and keep the magnetic hold and the rest of parts from the original. You'll need eight cylindrical magnets, three millimeters in diameter by two millimeters in height, that must be inserted during a print pause. Initially, I started with four magnets but kept increasing the number in several iterations until I had a reliable hold. [UPDATE 17/04/2019] This system still gets clogged with MDF fibers. It will work well for other types of wood and materials using at least these parts if you purchased the original vacuum adapter for the HF-500. For MDF, simply look for other adapters with a wider footprint.
