There is a new version please see (http://www.thingiverse.com/thing:1430039)

A dust shoe for Proxxon rotatory tool use as spindle for CNC machine. Pictured is a Shapeoko CNC. Using a 20mm motor mount, usually refer as (ID20mm Spindle Motor Mount Proxxon IB/E 50/E), This is a remake, the old version had a very wide and large body making it difficult to use as it will have a greater change to collide with hold-downs. Another issue was the screws attachment it was really not required and hard to remove/re-mount. This version is much easier to remove/re-mount making it quicker to change spindle tools.
