(You may notice the bottom part of the gauntlet has some of the glove underneath exposed. This is because when printing the 9+ hour part the heater and thermistor came out of the block and I had a thermal runaway... It was close enough done for me to just use it anyway.)
You will have to get creative with the print orientation and supports for this.
I printed the fingers at an angle of about -70 degrees x for the proximal and medial parts and 45 degrees x for the distal parts. For the others I printed them mostly vertically.
For the wrist and forearm if I just used brim it would fall off the build plate whether it was blue painters tape with glue or my PEI sheet. With a raft and 200% line width for the first layer and 55 degrees for the bed it stuck great to the PEI. I ended up printing them vertically as well and in an upright position instead of upside-down as you see in the stl file download.
