This is an adapter for a fairly standard ribbed vacuum hose. I based the design on the one I managed to break.
There are two parts to this (though they are included as a single model so that it prints in place as a unit), the lower part ‘screws’ onto the ribs of the hose, the upper part fits standard tool dust ports etc. The two parts rotate freely of each other (Assuming it prints ok)
so that you can connect to a tool but the hose is still free to spin etc.
I printed mine in PETG, 0.2mm, with minimal supports – I set slicer with an overhand threshold of 10, so only the base of the outer shell and the start of the internal threading get support.
The rest is designed to print without.
Took about 5.5 hours on a prusa mk3
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
