24/40 Keck Clip - ST/NS Glassware Taper Joint Clip

http://en.wikipedia.org/wiki/Ground_glass_joint#Joint_clips (ABS) Clip will weaken at temps of 90C and start yielding around 100C. Do not use for suspending large flasks or large assemblies if the clip will be exposed to temps in that range. After applying clip, always give the two joints a tug to make sure the clip has seated properly above the shoulder on the male joint. Print this clip with about 75% infill. If printed with solid infill, the connecting loops are prone to delamination at the apex which will eventually result in the loop splitting entirely. I printed mine @ 150 micron layer height, 5 surface layer, fast speed, no raft. -- 14/20 Keck Clip: http://www.thingiverse.com/thing:274395 19/22 Keck Clip: http://www.thingiverse.com/thing:275257 Instructions I recommend printing with about 75% infill and 4-5 layer surface. When printed solid, some of the connecting loops are prone to cracking at the apex and eventually splitting. I believe having less than solid infill allows the loops to distribute the flexing forces more evenly rather than concentrating at the crest. I haven't noticed any decrease in strength compared to the solid prints
