Flovv MoldLab
Upload your part as a STEP, STL, OBJ, or GLB file and Flovv MoldLab builds a complete, 3D-printable two-part mold box around it — top and bottom halves, alignment features, pour funnel, and air vents — ready to print and pour with Flovv materials. Try your first mold free — then $5/month for Flovv owners, $30/month for everyone else.
