The Plate and PCB assembly with mounting blocks attached is lowered into the keyboard chassis and captured within the top case when the bottom case is installed. A slight overlap of mounting block between the top and bottom case provides some isolation/dampening between the top case and bottom case halves of the keyboard for a natural \"force break\". ","images":["https://cdn.shopify.com/s/files/1/0279/3426/1330/files/SONNETV2_EXTRAS_BLOCKS.jpg?v=1718823188"],"price":10,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:53.421Z"},"share_url":"https://firestarter.network/l/lst_ToybKtMO","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
