IKEA Kivik Couch Armrest Table

In my apartment, I've got an IKEA Kivik couch. I like to use my PC on my large TV from the couch. I've also got a lot of remotes laying around, and the occasion drink. I've got storage and use problems. I had a slim endtable on the side, but it wasn't too helpful and it recently fell apart on me. I wondered if I could design something and 3D print a solution.

This is what I came up with, my second project since graduating from Tinkercad to Fusion 360. It is a modular table that rests on the low and wide armrest that makes the Kivik such a unique couch. With real estate like this, it was practically begging to be expanded upon.

The idea behind it is you can make this as big or small as you want. Each module is made of three pieces, two sides and the middle surface, measuring at a width of 100mm. I originally was planning to go big and sit my couch with six modules, which would cover from the end of the armrest to the start of the back cushion, but later realized that I only needed to go with three.

Big shout-out to Czex “Fusion God” of the Prusa Discord, who really lived up to their name and gave critical help to this project. I needed a way to connect the modules, and I didn't want to do something permanent like supergluing pegs. Czex designed the connector and hole, which allow for a tight fit that can still come apart.

Module Options

There are two surface options. One is plain. The other features cutouts for two cup holders and a slot for holding a smartphone. These holders do not have special connectors: they will need to be glued into the cutouts on the surface. The larger cup holder is 80mm wide, and fairly short. The smaller holder is 70mm but about twice as tall. The reason for the uncoventional design is to fit my use-case, the kind of bottles and cups I would typically use. The phone slot is long enough to fit an iPhone 15 Pro Max sideways.

There are two side options. One is plain, for the inside of the couch. The other, meant for the outside, features a small Honeycomb Storage Wall grid. This is for mounting holders for remotes and other items.

(Note: It wasn't until I was over halfway through design and print of this project that I realized I made a major mistake. The orientation of the hexagons are wrong! This causes everything to be mounted at 45 degrees. Which… once I had my holders mounted and my remotes in, I actually kinda like! Happy mistake I suppose. If there were demand, I might consider designing another side with fixed honeycombs.)

Printing Instructions

All STLs are oriented correctly. I like printing the middle pieces with the surface facing down, so I can get some bedplate texture on the surface.

Supports are not required for anything. I did use it for the phone/slot board, but I think it could be possible without. These cutouts are going to be covered anyway.

Highly recommend to print connector pieces in PETG. Test pieces were done in PLA, and one of them quickly broke. It would be functional, but expect some failures once you disconnect modules.

Add-ons

HSW parametric mount for any rectangular remote by Thiago Fonseca - These work really great for holding remotes of different sizes.

HSW Insert - Multipurpose Accessory Connector - HSW Mount by SB Artisan Creations - The remote holders have the simple hexagon insert, so you'll need these to fit them into the grid. I like this because it has added tension on the fit.
