While doing some research before I decide to purchase an X-Carve, I found a company who makes enclosures for small CNC machines. However, their enclosures only suit the 500mm X-Carve. You can order the enclosure to be 24 x 36 x 24, or 36 x 36 x 24.
Here is the information listed on their site: http://www.cadcamcadcam.com/enclosure.aspx
Ideal for office, classroom settings or apartment, where chip, dust, and coolant containment is a must. These heavy duty, clear-sided enclosures will fit most of the Sherline miniature machine tools, and the IMService CNC routers. The frame is constructed of aluminum, T-track extrusions, with handle(s) on the front door. There is a 2 3/8 inch, side opening for wires and hose pass through. The enclosure has an open bottom to permit secure mounting of the CNC machine to a bench top. The enclosure can be easily lifted off the machine if repairs or maintenance are needed. Use of this enclosure will dramatically reduce the noise level of the machine spindle, contain chip, swarf, dust and coolant spray, and reduce safety risks from broken tools or loosely mounted parts. The small enclosure has a hinged front door with magnetic latches( similar to the photo above), and the larger one has a vertical lift door with spring-loaded latches.
The enclosure is shipped disassembled, and requires only simple hand tools to assemble. Includes instructions and 2 brackets for mounting to tabletop.
