Heated enclosure for a Geeetech G2S Pro which is designed as an "add-on" to Delta G2S PSU Case/Stand by glendonwaldner, published Mar 10, 2016.
The case slips over the top of the printer and sits on the top plate. It has three extended legs that come all the way down and bolt to the CPU case using 3 printed flanged nuts and bolts. To achieve this you need to relocate your extruder to the centre or modify the case to suit your own set-up. When printing the flanged nut & bolts be careful not to over extrude or they get very tight! Just glue the flanged nut to the CPU case ... the heat enclosure slides over the bolt before tightening.
The case once bolted down also overcomes the need for diagonal braces. While I have carbon diagonal braces still in place, its only because I can't be bothered pulling the printer apart to remove them.
Sealing the case - the case comes down just past the heated plate (except for the extended legs for the lower attachment points) and has around a 20mm gap to the printers base plate all the way around. I use foam to block most of this off.
Venting - As there is an electric fan in Glendon Waldner's CPU case which sucks air from the base CPU case, I use that same suction (from the base case) to draw the fumes out of the upper heated enclosure and then it is all vented out of the room via some aluminium tubular ducting. It actually works surprisingly well.
Note this case only will work when combined with the PSU Case/Stand by glendonwaldner, published Mar 10, 2016.
Cut from Plexiglass 4.5mm clear sheet
I designed the case in sketchup and sent the DXF file to a local plastics company supply the acrylic (plexiglass) cut to size. The side pieces had a 30 degree bevel on their long sides so glueing it together with acrylic cement was and easy and resulted in nice clean joins. All up was under $200.
