I remixed this from one of my other designs https://www.thingiverse.com/thing:2207879 and adapted it for my Wanhao Duplicator I3.
I designed it so it wouldn't limit any movement of the axis.
If you make this, please let me know if everything fits together for your machine.
I used petg to print this to enure that the heat from the leds did not warp the led brackets.
Use a small brim to print the upper brackets.
4 - LED Brackets
4 - Lower adjustable pivot arms
4 - Upper adjustable pivot arms
1 - Upper Left Bracket
1 - Upper Right Bracket
The led strip I used is 12 Volts, and I directly wired the LEDs to the power supply (12 volt) and I also added a on - off switch.
I designed the adjustable pivots to snap in and hold firmly. Take some time and clean up the slot on the led brackets to ensure a good fit.
