Summary This is my second clip design and the one I am using. I designed a 1 tab and a 2 tab version. I have found that the 1 tab version works very well and I am not going to use the two tab version myself. The 2 tab version is designed to work the tabs under strands of filament to help stabilize the clip. /i found that the clip does not need to be stabilization. The through hole is 2.75 mm in diameter so 3mm filament will not go through it. I will upload a 3mm version.
