Triple 2.5" to 3.5" SSD/HDD Adapter

This adapter allows you to stuff THREE 2.5" SSDs/HDDs into a 3.5" drive bay.

Comes in different versions for universal compatibility.

3.5" HDDs are installed with #6-32 screws, while 2.5" drives use M3 screws.

I've made versions of the adapter that take M3 or#6-32 screws. You can mount this adapter with standard 3.5" HDD screws or switch to M3 screws for convenience. I've also included versions that take heat set inserts in the sides for improved durabillity.

For tooless 3.5" drive bays, use “Triple SSD 6-32”.

The full drive version is only for drive bays that rely on the full outer dimension of a 3.5" HDD instead of the screw holes.

All versions take M3 x 16mm socket head bolts for installing the 2.5" drives. You'll need 4 per drive.

Use either M3 x 5.7mm inserts or #6-32 x 7.1 mm inserts, as sold by CNC kitchen, Amazon, or Aliexpress. Shorter inserts would work as long as the insert diameter is around 4.6mm for the M3 inesrt and 5.4mm for the #6-32 insert.

You can easily fit in three 7mm drives or a 15mm drive with a thinner drive with enough room for cooling. You can fit in three 9.5mm drives, but I wouldn't reccommend that given the lack of room for airflow as shown in the third photo.

With 7mm SSDs, the spacing between the drives is a hair over 2.5mm. With a 15mm drive and a 7mm drive the spacing is a little over 4mm. I put in generous air channels around the drives for maximum cooling, but the drives may still run hot.

I recommend against printing this in PLA. Use a material that can survive in a computer case. I printed mine in PETG with 3 perimeters. Designed for 0.2mm layer height.

For cabling, Right angle connectors are out of the question, that includes daisy-chained power cable with the cable running perpenticular to the connector. A lot of splitters and some PSU SATA cables have the cable running straight out the rear of the connector and would work. If your PSU comes with right angle connectors just buy a 1 to 3 splitter style for each bay, or a 1 to 6 for a dual drive bay. Just be careful not to overload the SATA cable from your PSU. For triple drive installs you'll need connectors thinner than 9.5mm or 0.374" or a hair under 3/8".
