An open source 60% (15 by 5) ortholinear keyboard designed with both flexability and familiarity in mind.
- Highly customizable 60% ortho layout
- "Plateless" o-ring mounting
- 3D printable case
- UDB Support
The PCB supports many different layout options for the bottom row, embracing 1u keys but also with some left and right 1.5u modifier options.
The board also supports use of 2u keys in the usual TAB, LSHIFT, DELETE, and ENTER locations to maintain familiarity and speed with these often used modifiers.
NOTE: It is recommended to use screw-in stabilizers (yes they work with o-ring) due to clip-ins sometimes slipping between the three holes in the bottom row. I have slightly reduced the clip-in hole size which has mitigated the issue, but made them quite hard to push in.

Supports the Unified Daughterboard.
Supports a unique "plateless" o-ring mounting style. The PCB also has through-holes for plate mounting should that be preferred.
The "plateless" o-ring mounting style lets you enjoy the unique characteristics and sound of a platless + o-ring board with the added benefit of being able to remove/change the plate after soldering in the switches.
The printable plate files can be found in ./stls. There are two files, one for 1.5u spaced switches (pictured) and one for the 1u spaced switches. Only the left side plate is supplied, you will need to vertically mirror the file in your slicer to print the right side. The optimal printing orientation is upside-down.
A standard 60% o-ring (OD 180-190mm) with a diameter of 2.5-3.5mm will work.
NOTE: If you intend to use a layout with the
2uSHIFT or DELETE keys these plates may need modified in order to fit the stabs.
A 3D printable case designed around the "plateless" o-ring mounting system. It's a unibody design with a daughterboard cutout and recessed holes for 12mm rubber feet. The daughterboard is screwed into M2 threaded inserts.
Files for printing the case can be found in ./stls. The print has been split into two parts, since it is too large for standard-sized printer volumes. The two halves are designed to be glued together using key and slot guides for alignment and added strength. The optimal printing orientation is vertically with the case-sides facing down.
NOTE: I recommend using superglue to bond the two halves together.
- Glue all three keys into the slots of one of the halves.
- Add glue along the mating surface and in the slots of the other half.
- Carefully slide the two halves together using the keys and slots a guide.
- Clamp the halves together and let the glue dry for 10-20 minutes.
There is only one keymap avaliable for the keyboard currently. This keyboard has not been merged into the qmk repo yet. The firmware will need to be compiled and uploaded locally using QMK.
Copy ./qmk/keyboards into your /qmk_firmware folder then run the following command to compile the firmware:
qmk compile -kb legshark/rev2 -km default
NOTE: You will need to modify the keymaps to support different layouts!
