Larger Clearance: One For All | Cable Strap | Print In Place Clamp

thingiverse

[Update] I recalibrated my flow and it was about 3% over. Not enough to make a difference by itself but I successfully printed the original version (https://www.thingiverse.com/thing:5242299) with PETG by playing with Cura settings. I think PETG is just oozing and sticking too much on perimeters which means it needs more clearance, which can be achieved through changing the model (this remix) or changing the slicer settings to achieve a similar result. For the original design (https://www.thingiverse.com/thing:5242299), the Cura settings I used are: a fan speed of 100% all the time, "Outer Wall Inset"=0.14 and "Outer Wall Flow"=90%, infill 80%, 0.2mm layer height, 0.4mm width, 3 outer walls, support from the build plate. The "Horizontal expansion" setting on Cura can also be used instead of "Outer Wall Inset" and "Outer Wall Flow" Use the second version of the original model if the strap is too difficult to assemble, or some sanding... The clamping pressure is excellent and the bracket fits fine... ---------------- [Original text] I loved the original design and although many people printed it without issues, I had issues with the PETG I had. We could go on about why but I played with various slicers and setting but couldn't get it just right so I decided to just changed the clamp so it would work for my setup. I increased the clearance by 0.15mm for the hole where the strap attaches and for the bracket holes. I modified the pivot hole (elongated down and widened) and the tab position to give more space for the tab during printing without affecting the clamping action. I also extruded a bit under the clamping area to give some "spring" in case clamping is too tight. The pivot ends also have a bigger fillet. I tried printing it with 20% infill but I often had the pivot breaking near the holes when breaking apart the tab or during use. I suggest using 80% infill (14cm more filament compared to 20%), 3 wall line count, 0.2mm layer height, 0.4mm width and reduced outer wall flow to 94%. I used PETG carbon fiber. Once printed, break it by pulling the tab up a bit, not down. The strap might be quite tight once the tab is closed down. It might get a bit easier after a few cycles and it helps if the strap is long enough to grab it while opening. My clamp was tight enough for the strap to break by pulling hard, before it ever slid out. Only the clamp is changed, the other parts are available here: https://www.thingiverse.com/thing:5242299 Try the original first, it just might work with your setup.
