This is a PCIE support spacer for the Phanteks Premium GEN5 Vertical GPU Bracket riser cable.  I wanted some extra support underneath the PCIE connector on the bracket because I didn't like the flex it had.  This way it has some additional support when inserting or removing GPUs.  

The PCIE support spacer slips over the threaded studs on the bracket and has an overside relief for the riser cable connector.  The height of the PCIE support spacer should be flush or slightly under the threaded studs.

Printed with Prusament PETG Galaxy Black.  I recommend using PETG for better heat resistance over PLA.
