Description
This is a modular side table designed to fit securely on a 130mm wide sofa armrest. It uses a tight friction fit to remain stable without the need for permanent mounting.
The core of the design is the Slot-in System. The frame features 4x50mm slots on three sides (front, left, and right), allowing you to easily slide in and swap out various accessories depending on your needs or which side of the sofa you are sitting on.
Added a tighter fit version that worked better on my sofa. with an inner width of 100mm and a holder for 500ml cans.
The model comes with three different storage modules that slide perfectly into the 4x50mm slots:
1-Compartment Holder: Ideal for a phone or a large remote.
2-Compartment Holder: Perfect for splitting storage between two devices.
3-Compartment Holder: Great for organizing multiple remotes, pens, or smaller items.
Can Holder: For standard 500ml can (for example monster can).
To ensure high-quality surface finishes and an easy printing process, the table is designed in two main parts:
The Main Frame (with integrated mounting slots).
The Top Plate (featuring an 80mm diameter, 1.5mm deep recessed circle for glassware).
Assembly Hardware: The top plate is secured to the frame using 4x M3.5 x 10mm coarse thread screws (one in each corner). This provides a rock-solid connection and makes it easy to print the parts in contrasting colors.
Armrest Width: 130mm.
Slot Dimensions: 4mm x 50mm.
Cup Holder Diameter: 80mm.
Hardware: 4x 3.5 x 10mm coarse screws.
