Front Power Panel for 3D Printers

thingiverse

This is a small panel I'd designed originally for relocating the power "on/off" switch to the front of my CTC A10S "CR-10 knockoff", and for adding a LED volt meter for monitoring power supply voltage. I liked this design well enough that I used it on my Anet A8 Plus as well. Recently, I opted to add a provision for the LED volt meter on my original Anet A8's front mounted power switch housing and noticed that I never uploaded the design I made for the CTC. I'm just now getting around to uploading it. This model attaches, or is at least intended to attach to the front of a 20x20 aluminum extruded printer frame with two M4 screws and T-Nuts. Be advised that this model requires 28mm of clearance between the bottom of the frame to which it is mounted, and the surface the printer resides upon. When I installed this model on my CTC A10S, I'd already raised the printer for stand-alone conversion by adding 23mm tall extensions between the feet and the frame. My Anet A8 Plus came with taller feet from the factory, so I was able to get away with 8mm tall extensions between the feet and frame, which allowed me to use the factory screws. I'm including the foot extenders for both printers in case anyone has use for them. The 3 digit volt meters I'm using are an old bulk Ebay purchase I made years ago for unrelated projects. The red LED meters work at voltages from 2.5 to 30 volts DC, so they're fine for use on either 12 volt or 24 volt power supplies. The opening for the volt meter is 2.35 x 1.45 CM. A current listing for these volt meters describes them as 3.3 x 2.3 x 1.5(cm), 3.3CM being the outer measurement for the PCB mounting tangs, 2.3CM is the width, and 1.5 is an inaccurate measurement of the height. I know when I bought these meters years ago that I didn't pay more than $1 a piece, but they're going currently from $1.50 to $3.00 a piece on Ebay. The rocker switch opening is 2.2 x 2.9 CM. I print this face down as oriented in the STL with no supports. UPDATE: I added stand alone models for both a power switch and meter. The stand alone models are titled "Switch_Only" and "Meter Only" respectively. Perhaps somebody will find use for them.
