Wood and cardboard For the laser cutter, we stock sustainably sourced "RevolutionPly" plywood http://www.patriottimber.com/RevolutionPly-Plywood.php cut to 24" x 18." Scraps from previous projects are on the shelf and we encourage users to make use of scraps for smaller projects. We also stock 24" x 18" corrugated cardboard. Some scrap acrylic is available, left over from other projects. Extruded acrylic (good for cutting) is available at Lowes and cast acrylic is available from McMaster-Carr.
Fasteners We maintain an inventory of threaded fasteners. Look through the bins by the back door, or search this spreadsheet https://www.dropbox.com/s/5vktjn0vgqtcoav/screws.xls?dl=0 to look for a specific size. If there's something inexpensive that you need and we don't have it on hand, send the stock number from http://fastenal.com to Dr. Walker and we'll include your fastener on our next regular Fastenal pickup.
