This is the official design used by e-NABLE Brazil and if you are from e-NABLE Brazil's group please access http://e-nablebrasil.org/wp/cadaimpressaoconta/ to know how to print and assemble this device. This device has been tested and officially approved in Brazil for print and use in hospitals in Brazil.

Already tested in PLA (0.4 mm nozzle) and works very well, no support needed. Prints in 1h 23 min.

The new V2 headband (see picture) is narrower (it is 160 mm between temples (the original one was 170 mm) for better fit on most heads and also has shorter temples as to bring the total length to less than 132 mm. This way it fits smaller printers (Like for example Markforged Onyx One).

Also has "ears" at the ends, if the user prefers to utilize a strap instead of rubber band. The hooks for the rubber band had been reduced in size too. The height across the entire headband has also been reduced to 13 mm (except the "ears" area, where it is 19 mm).

The Bottom Reinforcement has also been changed (see picture). The holes and pins have been removed and the height has been reduced. The slot is slightly narrower too. NOTE: This works very well with the 0.5 to 0.8 mm sheets the folks are using in Brazil. If you are using different thickness or material, this may not work for you, so use the original bracket.

You can download the STL of both the headband and the bottom reinforcement. Attached is also the DXF of the new shield, without the holes on the bottom (see also picture).
