Here's my design for a small folding table designed to be used around the campsite. With two storage compartments inside, this makes for a great backpacking or day trip table. The table measures approx. 200 x 410 x 185 mm. My table is entirely 3D printed, aside from the hinge pins. The legs are even adjustable offering 3 different lengths (short, tall, combined).
The legs unscrew and snap into the 4 leg compartments for storage. One side has an internal storage compartment with a sliding lid. The second compartment is created by the other top when folded. The compartments are plenty large enough to store a number of supplies.
Fill the compartments with eating utensils, spices, fire starters, among other things, and you've got a great Grab-And-Go setup for backpacking. Print one out for each kid, and let them pack them full of crayons, games, and other activities.
That's right you can print this entire table. I've used two 2" 6D Finishing nails for the hinge pins on my table, but they are not necessary. The hinges fit together without gaps, so that means even a piece of filament can be cut and inserted as a hinge pin. Melt some filament to close up the hole, and you should be good to go for quite a while.
Filament can be used, but will wear out eventually. You can use a lot of different things for the pins such as toothpicks, coat hanger wire, nails, screws, whatever you have on will work.
My preferred hinge pins are finishing nails set in with a soldering iron. This table is designed to use two 2" 6D Finishing nails. The nails should slide into the hinges all the way to head, which should be too large. The holes can be drilled out with a 7/64" bit if the nail is too tight. Then, heat up your soldering iron, and once hot, press it gently into the head of the nail. After a few seconds, the nail should start sinking into the hole. Stop once the nail is flush with the hinge.
Not much to this print really. No supports needed for any of the pieces. I printed my table fairly quickly with a modified version of CHEP's Fast Cura Profile. I've included one of my Cura project files with the settings I've used here.
