This is a modified version of the PUC-Rio Ocolus De Protecao developed by Joao Victor Azvedo from the open source medical supplies website. The design has been optimized for injection molding and die cutting. This has passed design review by Protolabs as an injection moldable design. We have not ordered injection molded components and have done our validation only against FDM printed versions out of PLA. We recommend ordering a sample run to validate the design before ordering a large volume run.

The cradle of this design is also 3D printable on an FDM printer from PETG or PLA. We recommend using HP MJF for larger scale 3D printing as it allows for autoclaving the cradles for sterilization.

The plastic protective sheeting can be produced using laser cutting, die cutting, or hand trimming. We recommend die cutting for large scale production and laser cutting for small scale production. The plastic sheeting is 0.010in PETG sheets but a range of thicknesses from 0.010in  to 0.040in can be used. Alternative sources include presentation covers and overhead protector transparencies.
