Aegis Endo Shield (a.k.a Aeneas ENT Rigid Scope Aerosol Barrier 1.0)

thingiverse

This is a technical guide for creating a 3D printed endoscope frame and shim to protect medical professionals during procedures. The design aims to provide good protection, be easy to service, low-cost, fast printing, and printable on small 3D printer beds. ### Models Versions - **aegis-endo-shield** - original version of frame for the shield - **aegis-endo-shield-shim** - original version of shims or spacers used to make the fit of the endoscope to the frame tighter ### Credits * Dr. Justin Paber of Zamboanga City Medical Center. For the original concept for the protective barrier in the ENT community. * Mr. Renter Cafino of Zamboanga City Medical Center for the concept design together with Dr. Paber. * Dr. Joyce Rodvie Sagun of QCGH ENT-HNS Department for initiating the creation of this particular design with me, providing reference endoscopes used for the rapid prototyping, and testing the design. ### Release Notes **Sept 26, 2020** - Updated the credits section. Found out that there was already a concept circulating within the ENT community in Philippines prior, although there was no publicly available design available at the time of making of this design. - Credited both Dr. Paber and Mr. Cefino for the formulation of the concept. Basically Dr. Sagun contacted me and we produced this particular design, which was influenced by the concept from Dr. Paber and Mr. Cefino. Our goal was to address the immediate need for our frontline doctors at the time, which is i believe was successful. - Its always great to have concepts that results in various implementations, also it is important to credit those that initially thought of the idea, kudos! **April 16 2020** - Added **aegis-endo-shield.stl** and **aegis-endo-shim.stl** for the shield. ### Thing Files Guide * *aegis-endo-shield* - frame for the shield * *aegis-endo-shim* - shims or spacers used to make the fit of the endoscope to the frame tighter ### Objectives 1. Should provide good protection to the operator during procedures. 2. Can easily be serviced using simple tools. 3. Low cost that can be made and given to medical front liners. 4. Fast and easy printing, we need to be able to produce a lot in a short amount of time. 5. Printable on a small 3D printer bed, need to leverage all available printers out there. 6. Easy to assemble and limited post processing needed. ### Materials for construction: * 1 pc Acetate Sheet (A4 or Legal Short) or any plastic that is rigid (100 - 300 microns tested) * 1 3D Printed Endoscope Frame ### Printing Tips Printed this on ABS, since I am out of filaments. Be careful of warping, consider using raft of the thin arms, else it will lift. PLA should have no problem, but consider infill and durability. Please note, this is only a reference. Your printer setting might be different. Use whatever settings you deem *calibrated* for your printer. #### Layers - 0.30 - Layer Height - 3 - Top Solid Layer - 2 - Bottom Solid Layer - 1 - Outline or Perimeter Shells #### Speed - 70 mm s - Default Printing Speed - 80 mm s - XY Axis Movement Speed - 60% - Outline Underspeed - 80% - Infill Underspeed #### Extruder - 0.40 mm - Nozzle Diameter - 1.30 - Extrusion Multiplier (Simplify3D) - 130% Top or Bottom Extrusion Multiplier (Cura) - 0.80 - Extrusion Width - IMPORTANT!!! Makes printing 2x faster than 0.40! ### P.S. Fight hard against COVID-19! Regards from the Philippines.
