Air 2 - Jordan
by wasta, published
This is a printer frame based on the Air 2 by Mecano.
It can increase your print height by 60mm or 2.3 inches (depending on your hot end)
The printable height has been increased to 150mm (w/ Budaschnozzle) by extending the laser cut frame and flipping the z axis motors to the bottom of the printer. This printer can be assembled with the same smooth and threaded rods used for an Air 2 (The photos show a printer using 395mm smooth rods on all axis. The renders show the frame with the original Air 2 rod lengths)
This is a work in progress. Any and all suggestions for improvement are welcome.
EDIT: Added low-poly versions of frame and motor brackets for faster slicing.
190mm x 190mm x 150mm print area
z motors flipped to bottom of printer
printed braces for increased frame rigidity. (all braces moved to rear of frame for cleaner aesthetic.)
the top acrylic brace has been extended to the back of the printer to ensure square and make room for printed braces.
the crosspiece has been heightened / widened to increase strength and open up the build envelope
cable / filament routing
additional threaded brace / filament spool holder. (this is optional, but it seems to stiffen the frame. it is similar to Airwolf3d design but moved outside of 150mm printable area in z axis)
all curves from RepRap Air 2 design removed in favor of chamfers
unnecessary holes / slots removed.
- can use same "vitamins", smooth and threaded rods as or Air 2 (as shown smooth rods on z are cut to 395)
Design based largely on RepRap Air 2 by Mecano, ideas and parts from Lulzbot, Airwolf3d, and RepRapPro. thanks!

To make this printer... Laser cut the frame .dxf from 6mm material. The laser cut pieces can fit in an 18' x 24 laser on two sheets of material with about half a sheet left over.
Print the included frame brackets and motor brackets. I would recommend ABS for all parts with a generous infill on the frame brackets.
Assembly is basically the same as the Air 2, and the parts from the original BOM can be used.
The printer is shown with x ends from Airwolf3D, and a custom x carriage, but any x axis compatible with an i2 should work.
