A fully 3D-printable, true gasket-mounted 4x4 macropad engineered for a premium, ultra-smooth typing experience.
16-Key Matrix + Rotary Encoder
Engineered Leaf-Spring Plate providing a bouncy, trampoline-like typing fee
Utilizes 3D-printed "slip-on" gasket socks to sandwich the plate tabs, completely isolating the plate and PCB from the outer case.
Acoustic PCB Cushion

If you dont have TPU: Print the gaskets with PLA/PETG and don't print the cushion. The macropad will still be slightly flexible
| Part | Material | Key Settings |
|---|---|---|
| Top & Bottom CaseCase | PLA-CF / PLA | Wall Loops: 5 | Infill: 25% Gyroid | Layer: 0.16mm |
| Leaf-Spring Plate | PETG | Wall Loops: 4 | Layer: 0.15mm | Top/Bottom Layers: 5 |
| Gaskets (x4) | 95A TPU | Walls: 2 | Top/Bottom: 0 | Infill: 12% Gyroid | Speed: 3.5mm³/s |
| Cushion | 95A TPU | Walls: 1 | Top/Bottom: 0 | Infill: 6% Gyroid | Speed: 3.5mm³/s |
Note: For the TPU parts, setting Top and Bottom layers to 0 is critical, this exposes the Gyroid infill to create the "squish" effect.
Ensure all 3D-printed parts are cleaned of support material before starting.
Bottom Case
Add Cushion (if using TPU)
Assemble PCB (might be easier to add keycaps in the next step)
Add Plate
Put assembly on top of cushion
Put Gaskets on all four sides of plate
