3d printed jig for assembling LED cube layers

Includes a little jig off the side to bend the leads regularly, and holds the LEDs in consistent orientation using the cathode cutaway on the rim.

btw It is food safe to drink coffee next to 3d printed parts nerds ;)

P.S. this filament is awful, filamentium pla. The worst thing I've used since early reprap days when variability was high.

Any ideas what's causing that "shadowing" between the holes? those parts printed last I think but at the same speed/ironing pattern etc as the more matte parts between.

The "shadowing" is due to how it fills in the layers. The darker parts are done after the lighter parts, because it can't fill it all in one continuous line. Without the holes, it would just do one continuous line and it would look more even.
- Obvs but why the different finish? It should be the same temp and feed rate. It's weirding me out and I don't have the ability to image the surface to see the specific difference.
  
  Lower speed between the holes because of low acceleration. Because of this more heat is brought into the layer which makes it more shiny. Your nozzle doesn't reach the same speed on a 20mm line as it does on a 200mm line.
  
  You can try monotonic order for top/bottom. Not sure how it works with this many holes, but it usually works amazing for flat surface
