Silverware Tray

I wanted to build a silverware tray that had all of my utensils single-stacked and arranged as close to the front of the drawer as possible.

Supported utensils, with dimensions (total length x max width)

The tray is custom-designed to fit my drawer, 384mm wide x 264mm deep x 86mm high

I had to split it into 4 pieces to fit on my MK3S+ build plate.  I decided to join the pieces together with dogbone connectors instead of glue, fasteners, pins, etc.  They hold the pieces together well in my drawer, so I'm happy with it, but I'm sure there are better methods.

I printed mine in Sunlu white silk PLA+.  I used 0.15mm layers for the bottom 5mm where the base is and for the top 10mm where the chamfers are.  I used 0.3mm layers and 200% speed  (manually increased) for the layers in between.  I used 15% adaptive cubic infill.

I'm sure I could have saved material by using a shell and some clever supporting features, but after a half-hearted attempt, I just printed it with infill.  My total material was a bit more than 1kg.

I included print gcode files for printing the front pieces together or separately.  Obviously no need to print them twice.  

The dogbone connectors are set up to print sequentially.  They're nominally the same size as the holes in the larger parts, and they snapped together perfectly for me.  You may want to scale them down a tiny bit if you're having trouble with the fit.

If anybody wants the Fusion360 file, let me know and I'll try to share it.

EDIT April 6, 2023:

I added some bins behind the silverware tray to hold extra silverware, chopsticks, etc.  They are exactly a third of the width of the assembled tray and 250mm long (because that's the length of my print bed).  There was still 16mm left in the back of my drawer, and I was going to print some spacers to keep everything from sliding, but wife is smarter than I am and suggested just stuffing some paper behind them.  It worked perfectly…

I did have a little trouble with all of the big parts warping a little on the corners.  None of them were bad enough to ruin the print, and they all work fine, but I still didn't like it.  I tried a few things to try to avoid it, and I think the most successful was turning down the bed temperature after the first layer.  But there was still some slight curling up of two corners.
