Yet another paper tray design… This one holds an 8 1/2 x 11" piece of paper, preventing the cut paper from being blown around by the Glowforge fans. This paper tray is intended to replace the existing Glowforge Crumb Tray, sitting directly on the bottom of the Glowforge bottom surface; the height of the metal mesh is exactly the height of the Glowforge Crumb Tray. As such, there is no bottom on the box.
I apologize to anyone who is might want to duplicate this design. All of the non-wood components were random parts that I had lying around my basement. This included the following (w/ sources as I could find them):
- 3x 1/8" wood sheets
- 1x Stainless Steel metal mesh
- 1x 12v Lipo battery ← Could be replaced with an A23, or 8AA batteries
- 2x 50mm 12v fans
- 1x Rocker switch ← find your own switch and change the cutout on the pattern.
- 20x M3 screws, 16mm length
- 20x M3 nuts
- 1x small strip to metal
The metal mesh is squashed between two wooden border pieces, forming what looks like a picture frame with a mesh. Tightening the screws that hold the two wooden borders together seems to have made the metal mesh fairly rigid. The wire mesh “picture frame” is then glued to the vacuum tray, thus forming the top surface of the tray.
A last minute correction to the design included the addition of the four square braces on the inside corners of the box to improve the strength of the frame.
I also recommend placing a strip of metal underneath the battery to prevent the laser from accidentally cutting the battery (at least that seemed important to me because I used a Lipo battery.
Sorry, I can’t upload more pictures… The website says I’m a “new user” and can only upload three pictures. Maybe I’ll post more pictures when I’m older
