About this 3D model

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: 14x 608 skate bearings A scrap of PTFE tubing An electric screwdriver or drill with a bit cut from ¼ inch hex stock (most cheap quick change Philips bits in the US fit this requirement) 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 Change log 2023-05-28 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 2023-09-30 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 Add a printable spool 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!

There are a few improvements and accessories in development as remixes, check those out if you‘re up for the alpha/beta tester experience Adapter for 37mm gear motor Source spool holder for 5 KG spools Credits: @MiklosKiszely_486882 for the original idea @Psycho Shaft for the drag/tensioner concept thang010146 for YouTube videos of mechanical mechanisms, particularly the self reversing leadscrew for a level cable winder
