Powered Yarn Spinner · 模型 167961
This project is for those that have a need to spin yarn into a tightly meshed ball so that the yarn can be neatly stored or used. There are inexpensive manual yarn winders for this spinning purpose. These winders typically have a handle for the user to rotate to spin the yarn and costs typically US$20-30. Powered winders are also available, but at a much higher price of US$300-600. My project creates an electrically powered yarn winder. The electric winder sources some parts from a manual winder, adds an electric motor, all combined with custom designed 3D printed parts and powered by a USB port. I welcome those wishing to reproduce my yarn spinner as I built it. I do warn, this project is for an experienced builder. I've included a build guide to assist you in the construction. The following skills will be required: - Ability to cut steel - Ability to source like components. - Ability to 3D print my designed parts. - Ability to solder electrical wires. Parts List: - Yarn spinner (for parts) - 3D printed parts. - RS445-ST/18140/DV DC motor with 14 pins fitted gear. - MT3608 DC-DC inverter module. - 5mm 40mm bolt, washers and 2 nuts. - 6mm 20mm bolt, washers and 2 nuts. - Toggle switch SPST - USB-C panel mount socket. - Potentiometer 20KOhm, panel mount. - Resistor 10 Ohm, 0.25W - 5V LED indicator - 6mm knob - Electrical wire, typically 22awg. To get sufficient torque from the electric motor, gears are used. The two motor drive gears provide a ratio of about 3:1, transforming surplus speed into extra torque. The DC motor I used is a salvaged RS445-ST/18140/DV motor with a metal gear with 14 teeth. Ø=34mm x 52mm and weighs about 90g. These motors can be purchased new or used from around US$10. eg. https://www.ebay.com/itm/295128355202 The electric motor is a nominal 12V DC. I control the motor speed by starting with 5V from a USB source and via a buck inverter (MT3608), vary the voltage from 5 to around 12V. The motor typical is running at 3-4W of power, hence a simple 5W USB plug pack can comfortably power the unit. My print is made in PLA+ 1.75mm eSUN Gold filament, with 0.2mm layer height and 15% infill on a PRUSA I3 MK3S printer. Some parts will need print supports to properly form. I hope you can find this project useful, too.
