About this 3D model

It's my first design in Fusion 360, one point could be improved: the thinkness is 2mm, 3mm would be better. Box for X820 Geekworm board, for Raspberry Pi3B with SSD/HDD 2.5 drive. Bill of Materials (in addition to the materials supplied with X820 kit: https://geekworm.com/products/x820-v3-0-usb-3-0-2-5-inch-sata-hdd-ssd-storage-expansion-board): - 2 x Countersunk head screw M2.5 x 20mm: to close the box (in this case, you do not need install both screws close to the Raspberry header) - 4 x Countersunk head screw M3 x 6mm (or more): to hold the X820 board - 1 x mini pushbutton for power supply switch (example: https://www.gotronic.fr/art-bp-droit-sdt21s-16977.htm) - 1 x connector JST PH2.0 4 pin for power supply switch (example: https://www.gotronic.fr/art-10-connecteurs-femelles-jst-ph-4-pts-2-mm-22579.htm)
