UPDATE - The blower's design has changed, and I am redesigning my blower-hose adapter to fit the new model. The current files will no longer fit this blower.
Unlike other printers, the Press doesn't have much room on the print head for accessories like cooling fans, so you must either choose a very small (~25mm) fan, which doesn't move much air at all, or... why not just pipe in air from a large blower sitting outside the printer?
Using this blower assembly, I've greatly improved my ability to bridge gaps, and my prints turn out very nice.
NOTE: with this assembly attached to your print head, the printer still has a full range of motion, BUT, when you attach the hose to the assembly, it prevents your print head from coming all the way forward because it hits the frame of the printer, so be careful where you locate your parts on the bed when using this assembly.

Glue the parts together
Make sure you know how to strongly glue these parts together: I use ABS plastic with acetone.
