These sanding sticks hold replaceable sandpaper, glasspaper, ali oxide paper etc. They are 20mm wide and 150m long. They need paper 20mm x approx. 280mm long, it varies in length slightly between sticks. The paper is easily to replace with the thumbscrews and clamp. The photos show 3 of them, I’ve just added a 4th which is No2 with a square end. There’s a hole in one end of each of them to hang them up, it also reduces material costs.
You will need two 5mm hex head bolts with a thread length of 20mm along with 2 washers and nuts to match for each stick. The hex head bolts are recessed in the stick as are the nuts in the thumbscrews. I had to clean out the 5mm holes with a drill bit to allow the threaded portion of the bolt to slide through cleanly. I colour coded my thumbscrews for different grades of paper.
The sticks are printed on their side the way they are shown. All the printing was done with PLA at a layer height of 0.2mm. The sticks and clamp are printed at 50% fill and the thumbscrews at 100%.
Update – Following several requests I’ve expanded the sticks to be 30mm wide and added the files on here. They aren’t tested but should work ok.
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!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
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.
