A clearance is a deliberate small gap so parts can slide together. Thickness and kerf decide the actual size of a cut; clearance decides how snug the fit is.
Where clearances live
Select a component and look at its options:
| Option | Applies to | Effect |
|---|---|---|
| Joint fit clearance | Finger joints | Widens each notch by this amount |
| Divider slot clearance | Organizer dividers | Slot width = thickness + clearance |
| Lid clearance | Removable cap lid | Fixed at 0.3 mm per side between lip and walls; shown in the assumptions |
Adjusting fit
- Cut one test corner or one slot with a divider offcut.
- Too tight — first check the measured thickness; then increase the clearance by 0.05–0.1 mm.
- Too loose — check thickness and kerf compensation; then reduce the clearance.
Change one thing at a time, and write down what worked for each material.
