3D design & tolerances
Heat-set insert holes, print-in-place clearance, wall multiples and polygon smoothness.
3D design & tolerances
Heat-Set Insert Hole Sizing
Pilot hole diameter, depth and minimum boss OD for M2–M6 knurled brass heat-set inserts. Depth is insert length plus 0.8 mm so you do not punch through a thin boss.
3D design & tolerances
Polygon to Circle Resolution
How many polygon sides a cylinder of diameter D needs so chord height stays under a max deviation. For FDM pins, holes and vase-mode vases that should look round.
3D design & tolerances
Print-in-Place Tolerance
Size print-in-place clearance from your printer’s tested dimensional error plus a press, sliding or loose fit. Z uses a 1.4× penalty for layer lines.
3D design & tolerances
Wall Thickness vs Line Width
Round a CAD wall to an integer number of FDM lines so shells are not a thin leftover extrusion. Suggests line count, actual thickness and a line width that hits the target exactly.
