This is a speedloader for the WE M4 that I designed, based off of the original speedloader. I don't enjoy paying for stuff that i can print! This is not an exact copy of the original one by WE. I modeled this, created and printed it.
I only print with PLA, and I have not tested this item for durability yet, or put BBs in it yet. I wil update this creation with info as soon as i can test it.
The tip and the tube fit together a little tight, but you can either force it onto the tip, or sand the tube a little bit to make it fit nicer. The original follower piece fits onto this model perfectly fine, and vice versa. Print the tip with supports. The tube only needs supports from the buildplate, no internal supports are needed. I suggest printing the tube laying on it's side. If you have trouble printing some of these files (they are sorta small) then I suggest either using a raft, or slowing down your print speed.
To use this, you can A: put your finger over the tip hole, and fill with BBs, move it to the magazine, then push the follower down or B hold the loader onto the magazine, then load with BBs, and push down the follower.
