This is a component designed to work with my custom filament dryer. Its size and construction is constrained by the parameters dictated by the dryer component it must fit within.
It can be used as a stand alone spool holder with scale or as a simple spool holder without the scale. Instead of using bearings I printed low profile bushings that ride on 5mm shafts. I used M5x25 button head screws, as the head holds the shaft in place. Smaller diameter shafts could be used as long as the bushings spin freely. The width of the holder is enough to handle between 60-70mm wide spools.
The scale portion requires a couple of components that can be found on AliExpress or amazon. I purchased mine on AliExpress for about $12 CAD (module and sensor) including shipping. On amazon they will run about double the price. I was unable to locate the control module on amazon.ca (it might be available in different countries.)
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
