Under the table retractable bin/organiser

Use double sided tape to secure the slider under a table (screws would interfere with the slide unless you add some holes to the model, you'll have to add them yourself based on diameter of screws you use). Also added some dividers if you want to store stuff in it. There is also a test print to see how your printer manages the overhangs and stuff.

There are 2 versions of each slider. "Tight" doesn't have much wiggle space so the bin stays in place, not tilting much. Other one is better for people that don't have their printer calibrated perfectly, this one tilts a lot (after working on this project for longer than i'd like to admit, I consider that a feature not a bug :D), just print the bin with two slider holes and long slider to prevent tilting. Before mounting it slide the bin few times so it moves better when mounted (only for “tight” sliders).

I also made a video of how it works, it has the tilting version.

Trash can: 75x75mm (bottom), 100x100mm (top), height: 102mm

Slider lenght: 97mm (long 112mm), width: 30mm, height: 7mm.

Slider (filament): Version of the slider with piece of filament for securing it so it doesn't get off when it shouldn't. Just take a piece of filament (around 30mm long) heat it on one end with lighter and press it to make a flat surface bigger than hole on the slider. 

Slider (pin): Same as above but with a separately printed piece to secure it.

Let me know what you think :)
