I have been using wschadow's LED light holders for a while now and they were perfect for me. However with the MMU2 arriving the LED holders were in the path of the filament guide tube.
Hence I have taken wschadow's design as a basis and changed the following:
- increased the length,
- added a grid in it (to save some material and for the looks),
- changed the angle (these are a couple of degrees more vertical) and
- increased the size of the reces such that it is easier to run some cables behind the frame.
LED panels can be bought here: https://www.ebay.com/itm/283175875209?ViewItem=&item=283175875209
The "LED mount case" is untouched and is included here for convenience.
Update 7-10-2018; added a "LED mount case" with M3 slots and with increased size slot for the cable connector.
