This is a Compact Version for Smaller Printers. The printed size is 191mm long, 118mm wide, and 52.5mm tall version of https://3dprint.nih.gov/discover/3dpx-013359 DtM-v3.1 Face Shield PPE, 3D printable headband. Front size up to face shield remains unchanged; ear support was reduced by 25mm to fit smaller printers with a y-axis of 120mm. I am creating a 3D-printed headband in PLA, weighing roughly 50g/1.75oz per part. The outer envelope of the 3D-printed headband measures 191mm wide, 118mm long, and 52.5mm tall. Print time is approximately 3 hours per part. Acceptable alternative 3D printing materials include PETG, ABS, ASA, Nylon; however, printing in HIPS is not recommended. Build Time: 2 hours, 48 minutes Product Point of View: Healthcare workers responding to COVID-19 who face PPE supply gaps while waiting for domestic face shield production to catch up with demand NEED a transparent face shield that: Limits aerosol and splatter exposure from the front and above, providing top ventilation Reduces aerosol and splatter exposure on N95 and other face masks Is reusable for a single user (can withstand multiple daily washes; transparent visor can be replaced from readily sourced materials when worn out) Is easy to fabricate within a few days of design approval (ie no complex supply chains or production bottlenecks) Is comfortable to wear and easy to don and doff (as it will be taken on and off dozens of times in a twelve-hour shift) Provides protection to a broader area of the face compared to standard safety goggles or glasses Elastic for the headband: could be 7”x1/8” rubber bands, 13” strip of 3/4" wide buttonhole elastic, coflex/coban tape A standard transparency or overhead projector sheet or report-cover for the shield, 2-10mil (0.002-0.01”, 0.05-0.25mm) thickness Acceptable alternative materials include clear PETG, PMMA, or mylar in the same thicknesses; DO NOT laser-cut PVC Precautions: Clinicians and caregivers who have worn the device on service recommend adding a wrap of foam tape or "chest tube foam tape" to the headband to improve comfort; add layers of gauze or folded paper towel on the headband; dispose as necessary Before hole-punching, add tape (duct tape, medical cloth tape, etc) to reinforce the holes at the top of the transparency sheet during repeat use and washings; remove and replace tape between patients as necessary Instructions for Use and Assembly: Punch holes in standard A4 letter-sized transparency (297x210mm) with a standard two-hole-punch (approx 80mm distance with hole dia of 5.5mm); attach transparency to headband on the four mounting pegs Attach elastic to headband with cleats near temples, adjust to fit; some users may find 7” rubber band too tight, consider chaining elastic bands as necessary To clean, follow CDC recommendations in Strategies for Optimizing the Supply of Eye Protection - Selected Options for Reprocessing Eye Protection; DO NOT submerge or soak 3D-printed headband in cleaning solution as the headband may absorb the solution and leak it out onto the wearer’s forehead over time Discard and replace the transparent visor as appropriate, after excessive wear or fogging FDA Notice on Emergency Response: https://www.fda.gov/emergency-preparedness-response/coronavirus-disease-2019-covid-19/fda-notices-emergency-use-authorizations-and-investigational-device-exemptions
