Description

PDF

I tried another spool winder but found it finicky and delicate.

I designed this winder from scratch to be simple and robust, using the same self reversing leadscrew mechanism found on industrial cable winders

Why pick this model:

  • Prints on a single build plate
  • Doesn't require heat set inserts or exotic hardware
  • Fusion and STEP files are available, remixes welcomed
  • Generous clearances, simple mechanisms
  • Designed to be a tool, not a project

Print time:

  • ~500 grams of filament
  • ~22 hours on Bambu Lab X1
  • ~5 minute assembly
  • ~2 minute spool transfer

Hardware requirements:

Print settings:

  • Any. I used "0.16mm Optimal" in BambuSlicer with 5% adaptive cubic infill 
  • Use 100% concentric infill for spindle_male_driven
  • Try the STLs if you have a problem with the 3mf files. I’ve added (xN) to each file name so you know how many to print

Materials:

  • Any. I used Polyterra and iiidmax PLA+
  • Use TPU for tpu_consumable_wiper_blade. I used Priline 98a. The wiper blades aren’t 100% required but they help keep the windings nice and tight

Assembly and usage:

  • Demo video
  • Assembly video
  • The side that says “Pastamatic" needs to face outwards, away from the spool
  • The filament needs to come in under the target spool, like this: O____O
    • [not like this: O‾”‾”‾”O]
  • The drill/driver needs to run clockwise, as though you're screwing something in
  • Accelerate slowly until the winder gets started

    • Initial release
  • 2023-05-29
    • Fix a minor export glitch in "leadscrew_tooth"
    • Increase the number of “pin_short” instances in the 3mf from 6x to 8x
  • 2023-05-30
    • Add a second prearranged 3mf with two plates to avoid overlap warnings
    • Disable autogenerated brims for the single plate 3mf 
    • Add STLs for people who have trouble with the 3mf
  • 2023-06-03
    • Add a ring to passive_target_cradle to prevent the far end of the target spool lifting if a user lets the the drill hang loose
    • Add a pin to driven_target_cradle prevent the leadscrew popping out
    • Fix a minor clearance issue where a dovetail didn't fit quite right
  • 2023-06-05
    • Revert passive_target_cradle to the old drop-in style
    • Posted a spindle retention clip as a remix
  • 2023-09-30
    • Reduce chamfer on the crossbars to prevent them falling over when bed adhesion is poor
    • Add some holes to the crossbars to make them easier to screw down
    • Add some popular acessories to the all-in-one .3mf

How to contribute:

  • Post your make, it keeps me motivated to improve the model when I see people using it!
  • Post your feedback, idea or remix in the comments!
  • There are a few improvements and accessories in development as remixes, check those out if you‘re up for the alpha/beta tester experience
