I got sick of looking at the unused and uncovered spare bay in my computer case. I saw other drawers but decided to design my own. This drawer has 3 components: A housing to fit into the empty 5.25" bay, the drawer itself and the drawer face plate. The face plate is slotted and glued to the drawer. I made the drawer in multiple parts so I can test fit each component. If one part didn't fit, at least I wouldn't have to reprint the whole thing. I have an Ultra Blaster case and based my dimensions off of a standard cd rom drive. I used the existing "tool free" hardware from the ULTRA case to mount the housing to the bay frame. Attached is a drawing with outside dimensions of the housing and drawer face to compare to your specific computer case. The inside depth of the drawer is 161.25mm. More than enough for my extra usb sticks, flash cards, etc.

This drawer setup is a bit on the heavy duty side. The housing and drawer thickness is 1.75mm. With some light sanding on some of the edges, I was able to get my original drawer and housing to engage very nicely. To keep others from having this same issue I modified some of the inner dimensions so these parts fit together easier. Please let me know if it works out for you. I don't mind the post processing, but it would be nice for this to fit together right from the printer.

I have 2 types of drawer face plates - one with a 3mm hole in the center and a face plate that is solid. The hole was intended for adding a knob and screw if you choose to. The solid plate is just a basic starting point for those who want to modify it. In my picture I have a square cutout...just ignore that, it was part of a knob/grip project I'm still working on. I would love to hear your comments or see your makes. Enjoy.
