CNC Serving Trays That Actually Sell: What I Learned Making Them

Not every CNC project sells. Most don't. The ones that do have something specific going on — either they're deeply functional, they're visually distinctive, or they hit a niche that the buyer hasn't seen executed well before. These two tray designs do all three, and I want to explain why they work and what I figured out along the way.

Design 1: The Avocado Chips & Dip Tray

The avocado shape is one of those ideas that's immediately clear — the moment you see a tray shaped like an avocado with a round bowl where the pit goes and a longer area for chips, you understand it. That clarity is valuable. Buyers don't have to work to understand what they're looking at, which means the design can sell itself in a thumbnail or a listing photo.

The bowl for the dip is a pocket cut — about 3/4" deep with a slightly domed bottom that a finishing ball nose bit handles cleanly. The chip area is a shallow contour, more symbolic than functional — it defines the space visually without being a deep pocket that's hard to clean. The whole tray is one piece; no assembly.

What makes it actually sell: it's specific enough to be a gift without being so specific that nobody wants it. "Avocado-shaped serving tray" describes about 0.01% of the population, but that's still hundreds of thousands of people, and they all know someone who would love this. It shows up well in gift guides. It photographs well. The avocado green color you can get from a light dye on maple sells the idea even in a small image.

Design 2: The Brass Knuckles Serving Tray

This one is for a different audience entirely. Where the avocado tray goes to housewarming parties and Mother's Day baskets, the brass knuckles tray goes to the person with a motorcycle in the garage, a bar cart in the living room, and tattoos. It's attitude. The silhouette is a brass knuckle grip — four finger holes, thick body — and the tray pockets sit inside and around the form.

Technically it's a more interesting CNC job than the avocado — the pockets are deeper and the overall silhouette is more complex, but it's still a single-sided operation. Edges get a 1/8" roundover after cutting — that eases the sharpness while keeping the aggressive look of the form. A little sanding and it's done.

It sells well as a bar tray — for holding glasses, a bottle, a few snacks. The form is recognizable and a little transgressive in a fun way. People photograph it and post it. That social sharing matters for Etsy visibility.

CNC Considerations for Both Trays

Holding Methods

Carpet tape (sold as "woodworking tape" at a markup — just buy carpet tape) holds the blank flat on the spoilboard. A clamp on each end of the sheet for extra insurance. With a sharp bit and correct feeds and speeds, that's more than enough.

Feeds and Speeds

All feeds and speeds in the video are set for the Makita router and documented in the plans file that comes with the CNC template download. The plans also include a link to the section of the video that walks through setting up toolpaths in Carveco Maker.

Material

Both trays are cut from BAMX bamboo ply — specifically the bourbon color, which has a warm brown top and bottom ply. It's 3/4" thick, food safe, stable, and looks great finished. The 24"×36" sheet runs about $70 and fits both projects with yield to spare. You can use other materials, but this is what's in the video and what makes these look the way they do.

Finishing

After cutting, both trays get a 1/8" roundover on all edges, then sanding from 180 up to 240 grit. For finish, mineral oil is the simple option — cheap, food safe, easy to apply and maintain. For a step up, Geoff's Jank Wax — a food-safe beeswax and mineral oil blend made in the shop — gives a better feel and a little more protection.

Get the Files

CNC template files for both designs are available as digital downloads on Etsy — Avocado Chips & Dip tray files and Brass Knuckles tray files. Each includes the cut files and a document covering toolpaths with a link to the relevant video walkthrough in Carveco Maker.
