I really do not like the plates that hold the X rods in place on the LC v2. 1) They are wood, wood warps. 2) There capture area is tiny narrow and not at all rigid. So I decided to design my own X rod blocks, they grab on to twice as much rod and they hold the rods even, level, and ridged.
The little clear PLA face plate is a diffuser for a blue power on LED I am going to place in each one. If you do not want an LED, you can add color to the design by printing the plate a different non transparent color, or if you're a monochrome person,. Print both parts the same color. They press fit into the fixture.
If you do go with the LED idea, print the diffuser 1 wall in all directions with honeycomb and the honey comb will show through with the light. The actual X Rod Blocks should be 2 walls in all directions ~30% infill.
