These are devices for fixing sandpaper, which are suitable for manual grinding and for machine grinding.
Clamping and tensioning of the sandpaper is performed by rotating the inner cylinder with a slot with an 8 mm hex key. The end of the sandpaper strip is inserted into the slot of the inner cylinder. The beginning of the tape is attached in the slot on the base. If your sandpaper is paper-based and the grit index is high, it will be too thin. Then it makes sense to cut off longer and for better fastening fold it in half in those areas where the tape is attached in the slots.
Two models are made for manual grinding. In the form of a drop with a width of 40 mm, for fine grinding and for grinding in hard-to-reach places. In the form of a bar with a width of 80 mm, for grinding large open surfaces. If desired, the width of the models can be easily changed by simply pulling on the Z axis, in any 3D editor.
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.
