Ultra Simple Corner Clamp

I needed some simple corner clamps for gluing up laser cut projects. Most of the corner clamps I found both on Thingiverse and commercially were much too large for my small laser cut projects. This clamp is designed to print fast and holds just strong enough to glue up my projects. With a .8mm nozzle these print in about 30 minutes on my Ender 3 but I could probably print way faster. With the .4mm nozzle it took about 2 hours. Although the parts are separate they are designed to be able to be printed together if desired and the inner and outer clamp pieces can be rotated to fit within the clamp ring. There are two notches in the corner pieces so the clamp can be rotated 90 degrees as printed. Corner pieces are tapered at the bottom to prevent elephant footing from affecting the clamping surface.
