Day 6 — 26.06.2026: Designing the Top Case

Today I completed the design of the top case. I added all the required cutouts, including the Cherry MX switch openings, OLED display window, rotary encoder hole, USB Type-C opening, and the mounting holes. Most of the time was spent adjusting dimensions and fixing clearances, especially around the USB-C port, to make sure everything fit properly.

Note: The Lapse website was offline for most of the day, so although I worked for around 3 hours, only about 30 minutes of the session was recorded.

Time spent: 3 hrs

Day 7 — 27.06.2026: Heat-Set Inserts & Final Touches

Today I redesigned the mounting system to use M3 × 5 × 4 mm heat-set inserts. I updated all the standoffs, added chamfers to make installing the inserts easier, created counterbores for the screws, and rounded the outer corners of the enclosure to give the case a cleaner and more polished appearance.

Time spent: 2 hrs

Day 8 — 28.06.2026: Finalizing the Project & Shipping

Today I finished the enclosure by adding the final colours, refining the rounded corners, and making the last design adjustments. After completing the CAD work, I started learning CircuitPython and wrote a temporary firmware so the macropad would be functional for the initial build. With everything ready, I completed the documentation and submitted the project for shipping.

Time spent: 4.5 hrs
