After receiving inspiration from the excellent OpenSCAD H2 Model posted at https://forum.odroid.com/viewtopic.php?f=172&t=33824, I created a remix of the fantastic Raspberry Blade Center to house 3 ODROID-H2 units. I made the following changes to the original project:
- Migrated the files to SolidWorks
- Built an assembly
- Aligned the fasteners
- Widened the cart by 2mm so that it would remain fit in its place
- Made pillars for PSM brass inserts by both Heatlok and Minitech
The SolidWorks files are available at https://www.thingiverse.com/thing:3929164.
Figure 5 - The design of the caddy
Figure 6 - The design of the caddy
- 4x Rods, M6x44.5 cm (Metal or Nylon)
- 4x M6 Nuts
- Optional 32x M3 HeatLok Brass Inserts from PSM International or similar.
- Optional 32x M3x5mm screws for Insert Version
- Optional 32x self tapping screws 5-6mm long (hole is 2.5mm wide)
- 8x H2 Caddy (either Inserts or Self tapping version) Version with inserts recommended, but requires brass inserts.
- 8x H2 Mount part (vanilla, pressfit or pressfit&tab version) recommended the one with tab.
- 1x Ear Left
- 1x Ear Right
- 8x H2 Boards
- 3U available in a rack (small depth/network rack is OK)
I have not tested the Self-tapping screws version of the caddy The distributed PSU is not rack friendly.
ODROID-H2 Design Feedback For the particular use case of using the H2 as a rack blade, the following issues have been found:
- The audio connectors are too tall, and should stay within the limits of the other connectors
- The positioning of the power/reset switches is inconvenient, and it would be better to have them in the front of the caddy
- The positioning of the LEDs is also inconvenient
