Under Machine Drip Tray for DeLonghi Magnifica Bean to cup coffee machine ESAM4200.S

The drip tray consists of two parts, the base, which holds the drips and a grid that sits over the top. After I made and tested it, I think you can skip the grid on the top. 

There are specific feet locations that the coffee machine sits upon. I personally like the grid on the top, as it feels more complete, but the coffee machine sits on the foot pads making the grid unnecessary.

I have included an image of the coffee machine, to help you identify which one it is.

My Ender 3 S1 is too small to print it in one piece, so I split the model up into parts and glued them together.

To remove the grid, simply push down on one of the solid ends and it pops right up making removal easy. Tipping the content into the sink also make the grid come off :) 

There is plenty of room between the inside of the base and the grid. 3mm clearance all round, so it's easy to print and no risk of parts getting stuck/jammed together.

Models

I have included the full models, without the cuts, so if you have a printer capable of doing it in one shot, there is a model. I have also included the cut version that I used.

The grid also is in a single part and in the cut sections. There is no need to glue the grid together. It was designed to cut into four parts, but I only needed to do two. 

I have included the Fusion 360 model, so you can modify it to suite your own coffee machine, if the dimensions are different. Change the parameters to adjust the base sketch.

There are also two STEP files, one for the base the other for the grid.

Print

Use the setting you prefer, but I used the following and it seems to work fine.

If you want to cut the model yourself, dovetails might be a good choice. I chose none, to play it safe.

Base

Print with the bottom on the print bed. This will give you the best surfaces and the cleanest print.

• Top/Bottom: 3
• Nozzle: 0.4mm
• Layer height: 0.2mm
• Infill: 3D cubic
• Top/Bottom pattern: Lines

Infill is not all that important, as there is only a few mm of it.

Grid

Print with the top on the print bed. That is with the pegs or legs pointing up.

• Top/Bottom: 3
• Nozzle: 0.4mm
• Layer height: 0.2mm
• Infill: 3D cubic
• Top pattern: Concentric
• Bottom pattern: Lines

Infill is not all that important, as there is only a few mm of it and it should NOT be weight bearing.

Materials

This is where I might have made a mistake. I used Black PLA (to fit in with the look of the coffee machine). I chose this rather than PETG, because I have some experience gluing PLA and none gluing PETG. I went the safe route.

The Purple grid, I used PETG.

Construction (if you use the parts)

Put grease proof paper down (the kind you use for cooking) make sure it is large enough to give you plenty or work room.

Once you have determined which way with parts to, arrange them on the paper. 

Prepare your superglue.

Remember - Measure twice, glue once.

Glue two parts together, simply run a bead of glue down one side and push them together. I used a place mat to guarantee that the two pieces were aligned straight. This is important for later.

Glue the second pair the same way. Now leave them to dry for an hour or two.

Time passes.

Repeat the process gluing the remaining two parts together. If they are stuck to the greaseproof paper, don't worry, that happens if you had glue come out the bottom. Sometimes it does, sometimes it doesn't.

Leave the now completed tray to dry/cure over night. This will have taken a long time to get to here and there's no point in rushing now.

Waterproofing

Use isopropyl (IPA) to clean the surfaces of any grease and dust. You need a good surface for the waterproofer to adhere to.

To waterproof the base, I used MG Chemicals Silicone Modified Conformal Coating. I sprayed 4 (four) very thing coats onto the top surfaces. I did this outside in a well ventilated place (by the recycling bins, they are a good height for this). I left it about 45 minutes between coats.

You could use epoxy or some other coating.

Leave to dry overnight, there is no point in rushing at this point and ruining the part.
