Emmett’s print-in-place secret heart box remix has become a desktop 3D printing classic — twisting the heart into a rounded cylinder and back into a heart never fails to get oohs and ahhs. And around Valentine’s Day you actually might have good ideas for things to put inside the box! Emmet has added a feature to permit you to add text to the box as well.
I really enjoyed Eric Young’s design of his Secret Heart Box, but I didn’t relish hunting down all the required parts to put it together. One thing I learned from designing the Blossoming Lamp is that it’s entirely possible to 3D print complex, preassembled mechanisms without breaking the 45-degree rule. I took it as a challenge to show that it’s possible even with something as seemingly complex as this locking heart box. See the video here.
UPDATE: By popular demand, I’ve modified the customizer code so you can now add words to the top of the heart. Make sure your valentine knows it’s just for them.
A big Thank You to the good people at Makerbot and the bot farm for printing 100 of these as favors for my wedding. It’s good to have a friend with a factory.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
