Model Description

Model ID 3DPX-014017Category Labware & DevicesDevice Use General Equipment or AdapterKeyword(s) 3D print Face shield; FDM; Plastic; PPE; Face shield adapterThe strap adapter converts the strap hooks on the back of a 3D printed protective face shield frame to slots. The hooks were originally designed to be used with an elastic strap with slits (i.e. “buttonhole” elastic). The adapter allows the tourniquet strap to be attached and adjusted to a comfortable size for each user without cutting slits in the strap. An existing strap with slits can also be used with the adapter and adjusted for comfort.3D Modeling/CAD Software Fusion 360 / SolidworksModel Origin Custom illustration/CADPrinter Technology/Material Material ExtrusionPrinter Make/Model Prusa i3 MK3SPrinter-specific Build Instructions Build file Binary Data WashU_SlotConversionThin_for_PrusaShield_0.3mm_PETG_MK3S_16m.gcodeSpecific material PETGNumber of prints per build 2Build time 16 min (thin)Build file Binary Data WashU_SlotConversion_for_PrusaShield_0.3mm_PETG_MK3S_18m.gcodeSpecific material PETGNumber of prints per build 2Build time 18 min (standard)Pre- and Postprocessing Instructions Slicer program and layer height will determine the thickness of the adapter.
