This is a fun and easy project that involves electronics, 3D printing and laser/CNC engraving.
3D printed base:
The base is designed to fit 3mm acrylic sheet. (+0.1mm clearance in design) 3 different lengths are attached.
V2.0 is for 15cm acrylic sheet, V2.1 is for 18cm and V2.2 is for 9cm.
1) 3mm Acrylic sheet is cut to size.
2) laser engrave pattern
There are 3 xdf files (but myminifactory does not support dxf);
- rose pattern
- roadrunner pattern
- Original Lion pattern created by UnpredictableLab which was projected to 2D dxf:
To create your own pattern use canvas feature in Fusion 360 to trace an immage.
If you don't have access to a laser cutter or CNC you can use a multi-tool (Dremmel) and engrave manually with a printout under the sheet.
The base is designed for 9mm wide LED strip that slides in from the side. The strip is powered via USB or battery pack. The USB can be used from any old computer mouse or keyboard. It allows the lamp to be used from both computer port or phone charger as shown in the images.
Note: depending on voltage rating of your LEDs you might need resistors. I used 100 Ohms SMD on the strip.
Have fun printing and building!
