3D printing something to wear on your arm is very uncomfortable. (unless it is FLEX)
You should rather do something like I did: https://www.reddit.com/r/raspberry_pi/comments/5n14e1/raspberry_pi_zero_programmed_clock_on_my_arm/

This was posted a while ago, and I've made a ton of improvements over the last months/year

Great design! It'd be awesome to make a bottom that fits the Adafruit low profile micro SD holder (http://www.adafruit.com/products/966)http://www.adafruit.com/produc... so it doesn't stick out so much on your arm. If I knew CAD I'd do it myself.

have you considered batteries? ;)

I'm using a laptop battery in my backpack right now.

right :) maybe you could make a batteryholder in a lower-arm mount? :D

Do you (or anybody else) have rechargeable Li-Ion recommendation for the Pi?

Another note, the Host USB ports on the Pi connected to the main 5V power rail on the PI. This is an unfused connection (so do it at your own risk), but I actually powered my Pi via the host USB port, since the thing I was attaching it could supply steady 5V power. This enables to you have just one wire running in the right direction from the pi.

I used the powersupply from http://www.thingiverse.com/thing:26814http://www.thingiverse.com/thi.... The batteries that are connected are 18650 cells, 3 of some random laptop battery, configured as 3SP1 so supplying ~11.1 volt.

Front for Voltage Regulator Board

Reminds me of the "Glitch Tool" from that old tv show Reboot. lol

Now put a glove with bend sensors on it and program it for chorded key entry and you'll have a fully portable setup.

Oh, crap, I want to do this now. Only no LED, I'd put an actual 3.5" monitor on it. Oooh, baby.
