Ender 3 Light Bar - Brackets
Description
These are brackets for a led light bar mounted on top of the Ender 3 printer frame. The brackets fit to the side of the top frame, have a rocker switch to turn the light on and off. I've connected mine to the printer power supply. Make sure you either have 24V led strips or you connect 2 12V led strips in series, (or use a dc-dc convertor). I've printed mine in PETG on a Ender 3 v2. Things you need for the assembly The 2 brackets, left and right Rocker switch, (19mm x 12mm ) 18 mm aluminum led strip channel, 325mm length 24 led strip, approx. 300mm length (or 2 x 12v strips connected in series) 24awg wire spade connectors for the power supply I also used a small 2 pin molex connection near the light bar for serviceability 2 x M4 20mm screws TODO: while the design works as is, there's a few things that can be improved (maybe another afternoon to redesign) add ribs top the cut-off channel to improve strength make sidewalls thicker, the top wall is only 1mm thick and feels a bit thin see if rocker switch can be mounted horizontally to reduce the side footprint add a few more fillets and roundovers to improve strength
