Important Note: This mod works on Trident 300 and 350 builds ONLY. 250 build simply has no space needed to accomodate the holder and the spool. Sliding 8mm linear guides allows for adjustable spool width. Supported spool size is 200mm in diameter and up to max 75mm wide, typical for spools up to 1kg - 1.2kg. Changelog 08.05.2022. Initial Release 20.05.2022. Added new PTFE guide with tilted opening that guides the PTFE slightly to the left to prevent sharp bends. Just one lower guide is recommended now with this new top guide. Why? Over the years i've been getting nicer prints and almost 100% eliminated wet filament ooze by placing the filament spool inside of enclosed chamber. Since my printers work almost 24/7, chambers are always hot enough to keep the filament dry and produce perfect prints. Print Setup All parts are printed without supports. Recommended material is ABS/ASA. Recommended perimeter count is 4 and 5 top/bottom layers with infil from 30% . All parts in STL already have correct orientation, just import and print.

Why? If you are building Voron 300mm2 or 350mm2, V2.4 or Trident, you will soon discover you need a larger/deeper desk to accomodate your new machine, also if you have 5.5 or larger display mod you will end up with the printer being backed up against the wall and not enough space for the spool holder. After encountering the problem i've started messing with different designns that would provide stable, easily accessible place for the filament spool while keeping the filament path as short as possible. Print All parts are printed without supports. Recommended material is ABS/ASA but PETG or even PLA can be used as well. Frame extrusions get hot during long prints under enclosure so be carefull with PLA. Recommended perimeter count is 4 and 5 top/bottom layers with infil from 20% . All parts in STL already have correct orientation, just import and print. STL File naming: Classic__part_name.stl - Parts for Classic Voron spool holder design BB__part_name.stl - Ball Bearing Version parts Versions: 1. Ball Bearing Version 2. Classic Voron type spool holder Ball Bearing Version This version uses 100mm x 8mm rod for spool core mounting. Provides very smooth motion and virtually no resitatnce to the spool motion. The downside of this design is that the spool can free sping and cause the filament to jump off the spool and entangle.Since my printer is very close to the wall the wall itself servers as a resistance to the filament and prevents any free spinning and filament slipping off the spool. Ball Bearing version - BOM S-F-608-ZZ Bearings 1x 10mm x 8mm steel rod with cut internal M4 threads on both ends (easy to find on any mechatronics shop and easy to DIY) 10 M5x10 BHCS 4x M5x16 BHCS 4x M5 Hex Nut Classic Voron type spool holder This version uses classic Voron spool holder design adopted to fit the spool holder arm. This design is recommended as it greatly reduces/eliminates the risk of free spinning of the spool and filament slipping over the spool. This version is also simpler/easier and cheaper to make.
