A simplified PCB card guide or board retaining clip for assemblies, boards 1 to 2.4 mm thick, any length.
An 8 mm wide, 6 mm high bar along X, centred on the origin, its base on the XY plane, with a board slot along its top from 1.8 mm above the base, as wide as the board plus 0.3 mm:
| Board | 1 | 1.2 | 1.6 | 2 | 2.4 |
|---|---|---|---|---|---|
| Slot width | 1.3 | 1.5 | 1.9 | 2.3 | 2.7 |
| Parameter | Meaning |
|---|---|
kind |
guide or retain-clip |
board |
board thickness, mm |
length |
mm (the clip's lip adds 1 mm) |
material |
unspecified (no material assigned), nylon (PA6), pom |
No standard covers these generic guides and they name no maker. The geometry was measured from the published reference models below (every planar face read; the same body for every board and length), and every preset is checked against its own model: bounding box within 0.05 mm and volume within 2 %.

A simplified PCB card guide for assemblies: an 8 x 6 mm bar with a board slot along its top (slot = board thickness + 0.3 mm), or a board retaining clip (the slot stopping short of one end, with an end lip). Boards 1, 1.2, 1.6, 2 and 2.4 mm thick, any length. Measured from step.parts' published models (MIT); no standard or maker drawing covers these generic guides. Along X, centred on the origin, base on the XY plane. Dimensions and attribution: see the README.
