Tonio emailed me these photos of a handguard for a Tippman paintball gun designed by a colleague of his and then printed on a Dimension Elite 3D Printer. The handguard incorporates three picatinny rails, an angled forgrip and a flashlight mount.

The Dimension Elite 3D Printer prints a polymer called ABSplus. Tonio reports it has been tough enough to survive a few paintballs games without damage.
