Anti-Warping Walls

Various posts note the benefits of printing a thermal baffle around a print to slow cooling and decrease warping. These little walls are recyclable versions which you can reuse and place around the boundary of the object as it starts printing. 1 wall uses 10cm of 3mm filament.
Adjust the SCAD depending on your x-carriage clearance, layer thickness and width, and feel free to modify if you wish alternative shapes...
Don't forget to remove them before the print is finished if they're taller than the object, or set the code so the head lifts over the wall before parking.
A couple of possible enhancements would be

1. little feet so you could slide them in and they would stop in contact with the skirt to ensure they didn't get too close.
2. possibly some little handles to assist with extracting them from under a moving X-carriage.
