ESun Spool To 13mm Shaft Adapter

thingiverse

Quickie Update 11/30/16 - I've added a 1.1 version of the adapter to the files, which should fit snugly into ESun spools that have a center hole of 52mm in diameter, rather than the original's loose 51.8mm fit. This upgrade might not seem like much, but trust me, it makes all the difference when trying to get a tight grip on those pesky spools. This quickie adapter I designed is meant for ESun filament spools with a diameter of 13mm, allowing you to adapt them to work seamlessly with goldentuna1200's Quick Change ROBO Top Spool Holder. Simply print off two copies, insert them into the sides of your typical ESun spool, and voila! The spool will now fit neatly onto 13mm diameter pipe, which then slips effortlessly into goldentuna's top mount spool holder. If you try to simply place the pipe inside the massive hole that these spools normally have, you'll end up with a constant wobbling motion as the filament feeds. This adapter eliminates that problem entirely, allowing the spool to glide smoothly forward and potentially reducing or eliminating issues like machine vibration and excessive drag on the filament and extruder. My experience has shown that this adapter fits nearly perfectly as-is, but feel free to bump up the scale by 1% to nudge the diameter up or down by 0.5mm if needed. This design works beautifully in PETG, with plenty of strength and very low friction on smooth aluminum pipe. Just be sure to press it firmly into place, as I designed these adapters to fit tightly into the spool itself. This was done intentionally, because I found that loose adapters would eventually wobble out of the sides and cause all kinds of filament tangle chaos during long prints. As long as you're using ESun spools with a 52mm center hole, it should go in smoothly. By the way, check out my photo featuring ESun Solid Black PETG - fantastic stuff! I swear by their PETG and won't even touch PLA anymore. Once you get your head around PETG, you'll be hooked. Not as rigid, yes, but way more durable and prints neatly once you get it right. I recently tried using PLA again after a long time with PETG, and man... I was near about ready to lobby the whole 3D printing industry to change the name of PLA to "PIA", I was that irritated with it. This PETG is far better behaved. Plus, they have some truly pretty translucent colors - try the translucent blue, it's gorgeous. Print Settings: Printer Brand: Robo 3D Printer: R1 ABS + PLA Model Resolution: 0.2mm Infill: 100% Notes: Print this in a good, strong plastic with 100% solidity. You can eliminate support entirely if you like, but that may make it harder to insert your pipe during use since I included a countersunk edge to make insertion easier. Without support, the countersink may print badly or not at all, and the opening might deform. This is a very quick object, taking less than an hour each to print at 60mm/sec with 0.2 layer height. How I Designed This The Elves are happy this week... My designs are playing nice and minimal problems.
