Filmanent Sensor Switchbox #3DThursday #3DPrinting

Filament sensor switchbox remix for maplin roller microswitch by buxton Thingiverse

From buxton on Thingiverse:

The original Thing by bookmake was nearly a perfect fit for Maplin’s “Minature Microswitch with Roller” (Maplin product code N97AQ), except the gap for the lever arm and roller wasn’t quite right – didn’t extend far enough towards the left.

So, I took their STL in to Fusion360, cut away a bunch of the “out” side of the filament guide path. A test print revealed that the part was also a little too small along the Y-axis such that the switch was being clicked just by putting the microswitch in to position, so I stretched out the space between switch-holder and filament path by 1.5mm to solve that. (The part is not just rescaled in whole – I cut it in a couple of places and stretched just the necessary area.)

Unfortunately I wasn’t able to get Fusion to behave to resize the lid in the same way, so I just trimmed it back. It still works (the lid helps hold the switch in place), so I’ve called it “good enough”.

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!
