Since COVID we've been doing a lot of outdoor dining. Here is an adjustable clip to clamp the picnic table cloth in windy weather. The best thing about this clip is that it can be used for nearly any thickness of picnic table!

This is a revised design that integrates the slide and spring-release into one piece, eliminating the former pin and separate spring-release. This version also has printed-in teeth to improve grip to the table cloth and table. It is probably best to print this design in PETG instead of PLA to prevent fatigue of the spring release.

The primary clamp can be printed with no supports and probably no brim depending on your printer. The slide mechanism and spring-release can also be printed without supports on most printers, but may need supports if you have a cooling issue.

Note: Updated Nov 2022 to remove unsupported area on slide and to increase tolerance slightly.
