Ultimaker 3 Spool Holder

thingiverse

Love your Ultimaker 3 but hate the poorly designed spool holder it came with? Then give this re-engineered spool holder a try! Link to the source files can be found under the "Design Files" heading. WARNINGS: 1) Be sure to read "Print Settings" before printing (scaling is critical). 2) Read "Post-Printing" for assembly instructions and additional parts list before starting. UPDATE (VERIFIED): User junetaylor has confirmed this spool holder will fit a standard height UM3. NOTE: Most likely, you will not be able to use the cord cover (the white metal piece that snaps on and covers the RFID cord) on the standard height version. This spool holder was designed to address issues associated with the stock Ultimaker 3 spool holder. It is large enough to fit two 1 kg spools and can still be used with Ultimaker spools. It also completely rethinks the filament guide, making it far easier to use. No more taking it on and off to change spools and you can insert the filament into the guide after it has been loaded into the extruder. Spools with a center hub diameter of 52 mm or larger will work. Tested spools include (1 kg spools unless otherwise noted: MatterHackers Hatchbox Ultimaker 350 g Inland eSun (all fit on outside position, some cannot be used on inside position) MeltInk (verified by junetaylor) Innofil3D 750 g (verified by MathyV) Matteforge (verified by blobworks) Why I made this spool holder: When it comes to 3D printers, Ultimaker has a reputation for making quality machines that work out of the box. But this is their first venture into dual extrusion, and it shows. Most of the issues are small annoyances; bugs that will be worked out. But the spool holder leaves a lot of room for improvement. The most common complaint is that you cannot fit two 1 kilogram spools of filament on it. The filament guide that hooks onto the spool holder has a series of issues all by itself. It is awkward to use as it never wants to set right, it's too big for Ultimaker filament spools and too small for 1 kilogram spools, it hangs on the outside so you have to take it off every time you change spools, and you have to make sure to thread the filament through it before feeding into the extruder. Forget to thread the filament and you have to unload the filament and start over.
