Layer by Layer: Trinket Question Block Sound Jewelry #3DThursday #3DPrinting
The three part design includes the main case, top cover and diffusion piece.
Original solids for the case include:
• split ring hoop
• Trinket mounting and port openings
• openings for slide switch, clips to hold, chamfered bottom
The standoffs with cutout cylinders on the back will mount the large piezo to the back of the enclosure.
The opening for the piezo cables is located right underneath the slide switch opening.
To avid having a box or just a square around your neck, the 2D designed box gives it cool dynamic angle when wearing.
Created using the polygon sketch tool, we used a radius of 22 with 6 sides.
Extrude the shape and while still in extrusion mode, rotate around the object so you can get to the modifier handle.
Click on it to active how many degrees the object can slant, which in this case is -70.
To align up with the grid, I’ll rotate it by 30 degrees.
Select the bottom face to create the sketch. While extruding make sure to select the merge option in the small drop down next to the input box.
Next up, we’ll edit one of the corners to add perspective to the block by selecting two vertices a pushing them towards the center. Adjust the origin point by rotating the direction of the arrow.
The question marks were created with the text tool and then snapped to the front face of the cover.
Select the snap tool first, then select the bottom of the question mark, followed by the top face of the cover.
Lid for snap fitting the cover to case are easily adjustable to account for different tolerances, just scale the outer walls to get a tighter or looser fit.
The diffuser part is created using a sketch built from the bottom geometry of the cover using the project feature. Select the bottom of the lid, accept and move the sketch below the cover.
Select the middle sketch and extrude to .5mm. This is just enough to evenly diffuse the light around the enclosure. If the light isn’t even, move the LEDs around the enclosure until the light diffusion is even.

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!
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
