APX – High-Profile Angled Aluminum Case for Planck

From: $95

Introducing APX, an all new high-profile case for the Planck keyboard. Strong lines, chamfered edges, and a 3 degree angle set this apart. Proudly made in the USA.

Pre-Order Now

Pre-orders are now open and will run through May 31st. Estimated ship date is July 9th-11th to coincide with the Planck Rev 6 shipment. Add a Planck PCB and plate to your order below for a complete kit.

Fully compatible with the new Planck Rev 6 PCBs which can be added to your order. These will be shipped together when both are available. Rev 5 PCBs are also compatible if you have the hipro plates from OLKB or buy new plates.

These cases are only compatible with Planck Rev 5 or later PCBs – earlier PCBs can be made compatible by drilling the 2mm holes to make them 2.85mm – 3.25mm in size.

Plates are currently only available in a matte black anodized aluminum.

Finishing options include anodizing, powder coating, and Cerakote ceramic coating in a variety of colors. Cerakote colors are being finalized, previews coming soon.

This is a pre-order for a new product. The order will be submitted for manufacturing at the close of the pre-order period. The estimated ship date is July 9th-11th to coincide with the Planck rev 6 release. All pre-order sales are final.
