Extension winder

thingiverse

Winder for electric extension using a filament coil for 3D printing requires two 22 mm bearings with an 8 mm thick hole, measuring 7 mm. You can find these bearings anywhere you like, as they are commonly used in various applications. To complete the project, you will need an M5 screw with two nuts and two washers to secure the knob. The screw should be fixed so that it has minimal play while still allowing for smooth rotation. For the base and handle of the filament coil, you can use either iron or wood as the material. Simply drill a hole with a diameter of M8 and attach a piece of threaded bar with nuts and washers to secure the coil in place.
