• Model: 345.10 g
• Support: 5.65 g
• Total: 350.76 g

Total Estimation:

• Print Time: 9 hours 45 minutes

Key Design Features:

• Gyroid Infill at 10%: This infill strikes a balance between minimizing material use, optimizing heat management, and maintaining the necessary structural strength. It helps prevent the case from warping due to heat while keeping it lightweight and durable.
   
• Compact Dimensions: The case is designed to house a Low Profile-sized GPU, ensuring a small overall footprint and space efficiency. The inner length of the case is 22 cm and the height is 12.3 cm, allowing sufficient space for various components.
   
• Material and Finish: The case is designed for 3D printing with ABS, PLA+, or PETG, featuring a matte black finish (or customizable color options based on preference). It has been tested with ABS and PLA+ for reliability and strength.
   
• Power Supply Compatibility: The case is designed to fit a Pico PSU ATX High Mini-ITX Power Supply, either in a laying-down position or in a 90-degree position, offering flexible placement options depending on your build requirements.
   
• Oculink: The case is designed to fit an Oculink cable with the option to route it out from the front or back based on your preference.

Assembly Note:

• Please remove all support structures completely after printing to ensure smooth assembly.
• This case does not require brass knurled embedment nuts.
