3D printing

DFRobot 1.75 mm PLA in 1 kg spools makes up the bulk of the group, in over 15 colors. Specialty options include PVA in both diameters, NinjaFlex flexible filament, Proto-Pasta conductive PLA, and wood-fill. OverLord printer spares and OverLord printers round out the hardware side.

Breadboards

Solderless options run from 830- and 400-point boards to 4.5×3.5 cm minis and self-adhesive translucent boards. Adafruit Perma-Proto PCBs copy breadboard rail layout onto solderable copper, so a working layout transfers directly. SMT adapters bridge QFN, TQFP and SSOP parts to 2.54 mm.

Enclosures

Over 200 enclosures span board-specific aluminum Pi cases, generic ABS project boxes, DIN-rail housings and outdoor waterproof enclosures. Argon NEO, Argon ONE V2 and ARGON ONE V5 double as heatsinks; the V5 adds dual M.2 NVMe PCIe slots for the Raspberry Pi 5.

Mounting

M3 and M2 screw-and-nut sets, nylon and metal standoffs, LED holders in 5–10 mm, and DIN-rail PCB holders. Adafruit's M3 nylon stand-off set and Pimoroni's Pi standoffs handle the most common Raspberry Pi stacking heights.
