You'll need to have good adhesion with the build platform to print this successfully. It's 14.5 cm high, close to the maximum available for the Replicator and any catching of the print by the extruders will knock it off in short order.

If you use acceleration, you'll also need to have a current of cool air blowing on the print at least when it is printing the 45 degree overhangs, or else you'll get a blobby mess. The speed of the printer is too high to allow the plastic to cool fully before the next layer is put down.

Takes about 100 minutes on an accelerated Replicator. I recommend you use two shells and 25% infill to ensure it is strong.

The holes are there to help relieve stress. There is one persistent crack that appears in the center of the inner curve, but it is harmless.

The feet on the underside are rings with a 10mm inside diameter, so you can put 10mm adhesive rubber feet in them if you have them.

Note that there are layers in the Blender file for the holes and the feet, so these will not appear in the main model.
