Designed to be printed with 5 colors printer (ie MK3 + MMU2).
It can still be printed with less colors by merging parts in the slicer.

Supplies needed

• 12V LED Strip cut to get a load of about 6W:
  • example: https://www.amazon.fr/YXH-%C3%A9tanche-flexibles-%C3%89clairage-D%C3%A9coration/dp/B019Q6JVTO/ref=sr_1_8
• 12V Power supply (min 6W) with 5.5 plug. Better with integrated switch:
  • example: https://www.amazon.fr/gp/product/B07XQZ8X3Z/ref=ppx_yo_dt_b_asin_title_o01_s00
• Female 5.5 plug for case mount:
  • example: https://www.amazon.fr/gp/product/B08NCZBJD4/ref=ppx_yo_dt_b_asin_title_o01_s01
• 20mm diameter spring (length 50mm):
  • example: https://www.amazon.fr/gp/product/B07NVDRNXL/ref=ppx_yo_dt_b_asin_title_o01_s01
• 4xM3 screws for body mount:
  • min thread length: 10 mm
  • max thread length: 20 mm
• 4xM3 screws for door mount:
  • min thread length: 10 mm
  • max thread length: 17 mm
  • The design requires a round shaped head (ie Allen screws)

Printing

• The body+foot part needs supports on the bed,
• Every part of the Head must be printed with 100% infill:
  • We don't want to see the infill pattern through the shaders,
  • There are some lithophane effects on front part that require this as well,
• I used 0.2 mm layer height for head parts and 0.3 mm layer height for everything else but there is no real constraint on this parameter.

Source

Ready to print STL files are attached but the source code is available for modifications

• The source code is a scad file: https://github.com/GillesBouissac/agentscad/blob/master/things/minecraft/creeper-lamp
• Before opening the file you need to install the Basic Prerequisites of my library: https://github.com/GillesBouissac/agentscad/wiki/Prerequisites

Assembly

1) Insert cable in the body

2) Screw the 5.5 plug in the ground part

3) Screw the ground to the body

4) Solder the LED strip

5) Glue the LED around the body

6) Use strong Glue for the tip of the LED strip

7) Solder the wires in the ground part

8) Screw the ground door

9) You can add pads that will hide the screws and add grip

10) The body part is done after you add the spring

11) Head assembly

• Head shaders are all different and only left and right can be swapped,
• Before gluing them do some testing to be sure they fit well,
• You can glue head shaders in any order
