Combination of "Anycubic Kossel Plus Top Internal Spool holder" and "Low friction spool holder" for an Ultimaker

thingiverse

The low friction spool holder I've used for several Ultimakers has impressed me, and I liked the concept of an internal spool holder for my Anycubic Kossel. To combine both ideas, I used the two parts I designed. The "M8" thread version of the low friction spool holder is what I chose to use. By attaching the top and bottom part and three parts of the Anycubic holder with 6 x M3 screws and nuts - which are 16 mm long, I think - they're securely fastened together. Instead of modifying the internal spool holder's parts before printing, I assembled them with my own components and used an 8 mm drill to remove the blocks blocking the thread space.\r\n\r\nhttps://www.thingiverse.com/thing:2301167 : 3 x brazo.stl\r\nhttps://www.thingiverse.com/thing:235925 : 1 x 608_spacer.stl\r\n 1 x 608_core1.stl\r\n 1 x 608_core2.stl\r\n 1 x 608_nut.stl\r\n6 x M3 16 mm\r\n6 x M3 nut\r\n1 x M8 thread (120 mm?)\r\n3 x M8 nut\r\n2 x 608 bearings \r\n\r\nI've observed that adding a short Bowden tube in front of the feeder reduces the chance of filament falling from the spool.
