Filament Holder MMU2

thingiverse

Edit 4, December 18. I've added a new copy of the wide version with space for Festo Holders for those who want that option. Also, a version with 15mm extra internal width has been included (now 110mm between arms, 120mm total width). Check out this link: https://www.amazon.com/dp/B01IB81IHG/ref=cm_sw_r_cp_ep_dp_3lZLBbMAP6214. I've also added the Fusion 360 files for anyone who needs to modify this for extra or less width (just extrude the inner side/outer sides to get the correct width for your filament roll). I've been building a new enclosure with the filament rolls mounted on the back wall, so I haven't updated this in a while. For those who remix for extra or less width, please post your remixes to help others. Will post the rear-mounted holder that I've been working on soon, once the new enclosure is up and running. Edit 3. Very minor tweak: The rotating block has been removed from above printer models and replaced by four little blocks with holes for the PTFE tube to go through (ranging from 3.9mm-4.2mm), so you can print the size that fits your PTFE tube and snap it into the holder. Edit 2. New zip with updated versions that narrow the part where the tube is held to 7.8mm to reduce slippage. If already printed, use tape on rod there to reduce slippage or the new v1.1 of these files. Three new versions have been added: one with a different way to hold the PTFE tube at the end that should work better for above-printer use and lead to less curve/friction in the filament tube. Narrower versions of both have also been added, with 65mm between arms to suit the narrower version of the spool rewinder (75mm total width). The tube holder that fits onto the arm to hold the PTFE tube above is now included as well. It's a separate part otherwise it would be too tall to print on a standard MK3 and need support for the arm (created by Vincent Groenhuis https://www.thingiverse.com/VincentGroenhuis). For the version with the PTFE tube mounted vertically, it has the hole slightly shrunk to give a tighter fit (now 3.8mm rather than 4mm), along with the ability to rotate to change the angle as needed and extended legs to maintain the same size spool-holding ability. You will need supports just for the end part with the holder; however, with standard supports in Slic3r it will end at the bottom of the rotating box so shouldn't be hard to remove. This is designed to work with the auto-rewind spool holder by VincentGroenhuis https://www.thingiverse.com/thing:3200204?fbclid=IwAR3muTUUUXoFYZW7PbunU383HBHw0Ishxv6HkBoeAZEnvj1X8Q-IKU1ng7M. It has clearance to fit 95mm between sides to be big enough for larger rolls, yet only 105mm wide to be able to fit 5 in the lack enclosures if you trim the metal rods down from the 120mm they come from Prusa. Should have clearance for reels up to 225mm in diameter.
