I recently got a Macintosh Quadra 610 and nearly all of the internal plastic (and some of the external plastic) was shattered, just a byproduct of the era. I like adding SD-card hard drive replacements to my machines and since the drive sled was toast I decided to try my hand at making a new one that will support a BlueSCSI, a PiSCSI/RaSCSI, or a traditional hard drive.
Unfortunately, most PiSCSIs won't fit. You'll need to have a right-angle 50-pin SCSI connector, otherwise it will be too tall for the case, as shown in the photos here. Have fun removing the old connector!
If you'd like to mess around with this, I've included the SolidWorks for Makers files. You'll need the Apple Garamond font from here: https://www.dafont.com/apple-garamond.font
If you enjoy my stuff and feel like showing your support in a financial way, please feel free to donate to me on my ko-fi page. I make this stuff for fun, but a little scratch can make it even more fun :D
