Improved Adjustable Filament Spool Roller for Ender 3 S1

Improved Adjustable Filament Spool Roller for Ender 3 S1 Summary 4951629 was a v2 version of this filament Spool holder. Changed the main spool holder to be used in the Ender 3 S1 spool holder arm directly with no nut. Main support needs supports and it's kinda hard to get all of them out, but it's doable. Based on https://www.thingiverse.com/thing:4951629 Old Summary from 4951629 https://www.thingiverse.com/thing:3789524 JDs_Work designed this filament spool holder because they didn't like the way the original spool holder does not hold the spool centred on the axis of rotation (and neither did I). The holder is now compatible with 33mm to 90mm inside diameter filament spools allowing for a greater range of filament brands to be used. This self centring spool holder does not require any additional parts, components, or hardware other than the original bracketry which comes with the Creality Ender 3 range of 3D Printers and any other accessories you choose to use with it (i.e. a side mount bracket). It may be suitable for other printers depending on your existing bracketry, if you have a bracket which is flat with a ~30mm opening for the spool holder then this should fit. All versions of the Ender 3 are supported by this Spool Holder including the Ender 3, Ender 3 Pro and Ender 3 V2. This may also fit other printers in the Ender range i.e. the Ender 5, Ender 5 Pro etc. I have modified the nuts from JDs_Work's original files to increase the tolerance in the threads by 3% without changing the thread pitch, allowing the spool holder to be printed with a 0.4mm Nozzle with 0.2mm Layer Height, no supports on most of the parts (apart from the "Main Support" which requires supports on build plate only) and with minimal cleaning/post-printing steps. I used a 0.12mm layer height for improved performance but it prints fine and works just as well with 0.2mm. In this version, I have also increased the diameter of the main conical, self centring rollers to allow for a greater range of brands to be used i.e. SUNLU. I also added a textured grip to the back of each roller to allow for easier tightening and release of the spools. Despite the extra tolerance in the threads, compared to the original models, I would still advise that your printer is well calibrated and your slicer configuration is on point as the main feature of this design is threaded components which need to interface well. Print Settings Printer brand: Creality Printer: Ender 3 S1 Rafts: No Supports: No Resolution: 0.2mm Infill: 20% Filament brand: copymaster3D Filament color: Any color (printed in deep black) Filament material: PLA Notes: Supports are required on the "Main Support" component only. Part orientation may need to be adjusted to align the flat surfaces with the print bed. I recommend using the Auto Orientation plugin for Ultimaker Cura or similar depending on your slicer software. I used a Creality Ender 3 V2 to print these parts using the settings defined above (0.2mm layer height is quite rough for threaded parts but within tolerance) and they work as expected. If you use other materials, the amount of shrinkage may differ. If you would like me to make any further adjustments to the files or if they work well for you, please leave a comment as your feedback is appreciated. Post-Printing Optional Steps Some finishing may be required for rounding "sharp" edges after printing to improve the feel of the parts and make them less taxing to use, especially if you are changing filament often. The "Main Support" part requires supports so this will require the support material to be removed, trimmed and finished to improve the feel of the parts and to allow the other components to interface properly. I would also advise finishing (i.e. sanding) of the parts which interface as a bearing surface to make them as smooth as possible. Some light machine oil will also help reduce friction and allow the parts to move smoothly. IMPORTANT NOTE When selecting the type of oil to use, please ensure that it is safe to use with the materials you are using as some can react and cause unwanted results or even harmful gasses to be released.
