Lego M4

thingiverse

I created this standing upright with supports intact. It proved surprisingly simple to remove the supports afterwards. This one was printed in PLA, but I highly recommend ABS for its superior durability. If the handle doesn't fit comfortably in the hand, I simply apply a few gentle taps with a lighter, insert it into a Lego hand mold, and gently compress it to achieve a tighter seal.
