Upgraded Reel support roller bearing - Ender 3pro - 6 rollers

PREMISE: If you are interested in this project, also take a look at my Cult's design page, I have just made a new project that is much stronger and simpler to create. Reel support roller bearing for Ender3 pro. It is a roller bearing for Geeetech reel, the one having an internal diameter of approx. 72 mm. Normally the roller is placed on the pin of the Ender3 (diam. 30.4 mm) and unwinds, crawling laboriously and causing continuous overlaps of the plastic wire and fatiguing the wire pulling mechanism that sometimes clicks. With the roller bearing that I present here, this will no longer happen and the coil will unwind gently and uniformly. You can sleep peacefully while the printer works for you. The machine is all formed by interlocking pieces and ALL printed without supports. Look at the photographic sequence that helps with the assembly. must proceeds in this way: 1 - Temporarily remove the plastic thread spool 2 - Apply that 2 half-pipes above the original unwinding pin of Ender3 3 - Assemble the roller cage by inserting the roller pin into each hole in the ring nut (a small hammer is needed) 4 - Insert the rollers into each pin 5 - Position the upper ring nut and insert the pins one by one in sequence and gradually (with the help of a small hammer), until they are completely inserted into the holes. The bearing is now complete and ready to install. 6 - insert the roller bearing on the increased pin of the printer 7 - gradually insert the roller bearing retaining ring at the rear end of the pin 8 - that's all, now you can reassemble the spool of thread and enjoy the result
