These are feet that prevent a chair's legs from sinking into soft ground when weight is applied. The wide flare creates a higher surface area to allow for a much greater weight before they start to sink into soil or sand. The round tips still provide stable contact points for use on hard flat surfaces.

This is a revision of the "Sand Foot for Ultralight Packable Camp Chairs" (https://www.thingiverse.com/thing:4548638).

The design has been improved for both performance and printability. The foot has been made more robust so that it should be strong enough even at much smaller scale. It has also been designed to be printed without supports and without a heated chamber. (Any material can be used, but PETG will hold up to outdoor use much more than PLA. A high durometer TPU would also work well if your printer is capable.)

The previous design was a recreation of a foot design so that I could replace a missing one that looked identical to the others. This new sand foot is inspired by that simple design but with the improvements mentioned above.

3D printing settings This scale of this model was specially set to fit the Ozark Trail Compact Camp Chair from Walmart. Therefore the inner diameter (leg hole) is 12.65 mm. To make sure this will fit your brand of camp chair, simply scale the size of the print based on that dimension compared to the diameter of your chair's legs.

Remember that the tolerance is dependent on many factors including your printer and material, so I recommend you print one, or even just the bottom portion of one, in draft mode and test the fit on your chair before printing 4 in higher resolution.

Good bed adhesion is important for this print, especially if you don't have a heated chamber. I use hair spray on a glass bed.

Walls: 4 Infill: 25% Gyroid (but choose what you like best) Supports: No

My print time was 1 hr 26 minutes on a Voxelab Aquila.
