I must be using the wrong search term, but I don't seem to be able to find these (slides? guides?) anywhere.
They are used on the removable 3.5" hard drive. Anyone know where these can be found (preferably on Ebay, but OK if somewhere else in the USA.)
Thanks.
A common name for those is "rails". If you search on eBay for "hard drive rails" or "floppy drive rails" you will find a wide variety.
The challenge would be finding a set with the mounting holes in the right location and the overall shape of the rails that match your target system. If you can't find an exact match, maybe you can find a set that are close enough that they could be modified to fit without too much modification.
These are excellent candidates for a 3d printer.
