M2.5 Snap-Off PCB Spacer Sprue
A snap-off sprue of 16 round M2.5 PCB spacers, two each of 3, 4, 5, 6, 8, 10, 12 and 15 mm. Each is 7 mm OD with a 2.9 mm clearance bore, so you can stack them to reach any board-to-case gap for a Pi 4, Pi Zero or Arduino without hunting down odd-length M2.5 standoffs. The spacers hang off a 118 mm spine on thin 0.8 mm tabs that snap off cleanly. Every spacer sits flat on its end, so it prints square with no supports.
