Wanhao Duplicator i3 LED Light Bar by rasarmg

Last crawled date: 3 years, 1 month ago

Wanted a way to video record overnight 3D prints without leaving the room lights on. Since I had several Harbor Freight 3-1/2 in. 9 LED Mini Flashlights laying around, I decided to put them to use in this LED light bar design for my Monoprice Maker Select 3D printer (rebranded Wanhao Duplicator i3).
The required non-printed parts:
Six LED flashlights (often free at Harbor Freight).
Four 2mm small screws (can be replaced by glue).
Some small insulated wire to power the LEDs.
There are two light bar configurations: One that focuses all six LED downward in parallel (straight), and another that focuses each to a separate area of the Wanhao Duplicator' print bed when rear mounted (wanaho_rm).
Each configuration includes brackets for mounting the light bar in front (fm) of the the gantry, in view, or behind it (rm), hidden from view. The photos above of my installation show an example of the wanaho_rm mounted in the rear.
It should not take much effort to create a mounting bracket for other printers...
The measured operating power of the resulting light bar is 1.8 watts! So it should not impact your power bill if it runs continuously:)
Designs
Choose which lamp design bar and mounting configuration you prefer and print the required parts.
Although rendered STL models have been provided for each part with each configuration (see stl-models.zip), only two files are required from the list below to print all the parts needed to assemble a light bar.

For front or rear light bar mounting, replace Xm with fm or rm respectively in the second build plate.
