I made a hard drive holder because I have a rack server that has no space for hard drives inside of it. I made this shelving unit to house the three hard drives for the server-use www.makercase.com to create the outer shell -import into inventor -add shelves and tabs to receive shelf -export faces to illustrator -change print settings to 10% speed, 100% power and 5000 Hz for: Epilog Mini 18 Laser with a 40W laser and 18" x 12" print bed. -print -assemble -apply acrylic glue to joints -enjoy
