Pour opening
Auto opens the top whenever that costs little extra silicone; a shape that would waste a lot keeps the closed dome with a pour funnel.
Open top
This master is flat, so the mold is open at the top instead of domed. Pour silicone until it is level with the rim. No funnel, and nothing to trap air under a ceiling.
Pour spout width
40 mm
The pour opening (orange ring). Keep it modest on small models so the stand-fins still fit.
Stand-fins
4
Lets the mold stand upside down while casting. 0 turns it off.
Shell smoothing
9 mm
The cast detail comes from your master, not the shell. 0 hugs every bump.
Fit clearance
0.25 mm
Raise it if the tabs sit too tight.
Printer overhang limit
50°
Steepest overhang your printer handles. Shells draft to this so they print standing without supports.
Shell release
Easy release slides off undercuts. Exact hug stays tighter but can lock on non-convex models.
Base lock
Auto opens the base rib sideways when your model is wider above its foot than at it, so the walls slide off instead of having to be lifted. Locked keeps the tighter bottom seal; Off removes the rib and the locating pegs.
Printed clamps
Leave them out if you clamp with steel binder clips instead. The seats around the rim that stop a clip sliding stay either way.
Base clamp
Rim wrap follows the shape of the rim in a few short pieces, so it can't tip over the way the small clips can.
Master
Fused prints figure and base as one piece. Separate ships the figure with locating pegs, so you can print it in another material.
