So, my wife was saying that we have accumulated too much stuff in our kitchen drawers and we needed some way to mitigate all the crap we have stored there, so I got to work on making a sliding inset drawer that sits on top and in the upper gap of the cutlery drawer. the green outline shape in this image represents the inner dimensions of the drawer itself and the clearance to the 'ceiling' of the countertop.

this is the first half or "male" side of the sliding drawer. notice that the tabs are not the same size. the shorter one is the rearward side that sits on the back end of the drawer.

here is a closeup of the join, note that for printing I curved the corners to strengthen the join which also speeds up the printing process. Notice that the jointab is tapered, this ensures that the halves leave the least possible seam when joined and it locks into place more securely. note also that the angle is also outwards, so the angle is along at least two planes.

this is what the two halves look like joined. The tolerance gap here is 0.2mm. I could have made it much less, but I didn't want to waste a print, so I went the safe route. I have a 3d pen, so I figured if needed, I could weld the gaps shut using the same filament and then sand them down.

here is the finished tray. "It's just that easy!" Actually took about 8 hours to print each half, then I glued them together and welded the seam in the middle of the tray and then spent several hours sanding.

So, my wife also wanted better cutlery trays. The one we had before only had 4 slots, so I made these so that we had six and they spanned the entire interior of the drawer. I designed it so that it has clearance with the sliding drawer.

and here's what they look like installed. I ran out of white filament just past the mid mark on the second tray and had to switch to another filament. I wanted to use a filament that would be easy to paint over and this was the 'palest' that I had. when I showed my wife, she said that she liked it like that and doesn't want it painted afterall.

It has the added benefit of glowing in the dark. :D

You have admirable design skills. What program do you create with and what printer do you use?
TheOtherLucas
thank you! I really appreciate that. I primarily use sketchup for design iteration and for printing, I currently use a Bambu Lab A1, which is a great printer and very affordable and they didn't pay me to say that. :D

Remember to allow for adhesive thickness when designing tight fitting joints and interfaces. Many of the engineers I worked with in airplane interiors failed to allow for the ~.03" adhesive build up and everything they did was sloppy.

I actually made an allowance of 0.2mm tolerance between all the join surfaces for the smear of gorilla glue I used. also, it's designed to sit on the rail of the drawer, so there is no slop as the shape of the joins is complementary to the idle position. the join also has a load tolerance of about 50 pounds, which is far and away beyond the load that will ever go in that thing.

Excellent. A plane wouldn't fall apart on your watch.

I try to do my homework sir. :D
