Vacuum adapter for Stepcraft HF500

This is a 3d printable replacement for the Stepcraft vacuum adapter for HF500 spindle. I was having clogging issues with the original one wen 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 need 8 cylinder magnets 3mm diameter x 2mm height that need to be inserted with a print pause. I started with 4 magnets and kept increasing the number in several iterations until I had a reliable hold. [UPDATE 17/4/2019] This system still gets clogged with the MDF fibers. It will fit for other types of woods and materials, using at least the parts if you bought the original vacuum adapter for the HF-500. For MDF just look for other adapters with a wider footprint.
