Moon Lamp Battery Holder

Hi All,

I was inspired by https://www.instructables.com/Print-Your-Own-Moon/ and printed my own Moon

The biggest challenge was to install a light inside the moon. In India, I could not get a ready-made light that could fit gracefully inside the moon and stay portable. So in this instructable, I will share how I made my own battery holder and lit up the moon

Step 1: What Do We Need?

• 3D printer
• White PLA Filament
• 2 LEDs
• Switch ( 5mm x 2mm)
• 3 Coin cell battery: AG13, LR44, A76, 357

Software

• Tinkercad
• Cura

Step 2: 3D Print : Moon

• I got the 3d model from Leung CHAN
• Original link for his work, https://www.thingiverse.com/thing:2955930/
• He has several designs, but I choose a 3inch moon with 28mm hole
• Direct link for download https://www.thingiverse.com/download:5052942
• It took 6 hrs roughly, with no supports and 100% infill at 0.2 layer height

Step 3: Designing the Base

• I used Tinkercad to design the base
• It can hold 3 LR44 and a switch
• Locking mechanism to lock on the moon
• Download model from https://www.thingiverse.com/thing:4588379
• 3d print it at 100% scale, no supports needed

Step 4: Circuit

• Place the batteries in the tube
• Solder 2 LEDs in series
• Connect the battery, switch, and LEDs

Step 5: Finishing

• Slide the base on the Moon and rotate to lock in place
• Switch off the room light and switch the moon on
• Admire the moon lamp
