• First tray complete!

  Now I'm printing a funnel to test the concept. I made a few minor tweaks to the lid, and updated the files. They should be compatible with the already uploaded tray. Next I'll design a rack and print more trays. (and start using them actually).
  
  The lids fit very nicely. There's just the right amount of friction that it doesn't open on its own, but still opens easily by a finger or a tweezer which will be in your hand anyway.
  

• Lids are tricky to print

  I had a bad time trying to print a bunch of lids. The bed adhesion is good, but the hinge is a critical part, where it starts warping upward and hitting the extruder while printing the subsequent layers, which leads to detachment and failed prints. After tweaking some settings I got about 80% yield, which is much worse than 100%.
  
  Now I'm trying to print with supports around the hinges and hope that it will alleviate the problem. Problem is that the first few layers print out just fine, and then it gets progressively worse. I'm thinking about changing the cutout on the lid to be bigger, so the hinge doesn't stick out that much.
  

• First print

  I screwed up the first print because I was tinkering too much with the slic3r settings and got a terrible bed adhesion. Then for the night I had to pause the print, and as it cooled down, the tray has detached from the build plate. I'm printing it again, now with standard 0.2mm layer size.

  Putting a bunch of lids next to the tray is a bad idea; the lids will warp. Rather, do a separate job (maybe with a smaller layer height for the detail. I rendered a bunch of lids close to each other, and updated the files.

  It came out usable anyway, but the lids aren't that nice fitting. I also need more of them.
