Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4391322.

UPDATE: I've added a v2 which is larger but actually protects a 2207 motor pretty well.

There wasn't a full arm guard available that protected more than the extreme tip of the arm so decided to make my own.

Here is the OnShape link if you want to remix it, just please mention me or post the remix here on thingiverse so everyone can benefit :)
