Here is the rewritten text in a more polished and concise format: **PAPR Design Guide** This guide will walk you through the process of building a Portable Air Purification Respirator (PAPR) using 3D printing and readily available materials. **Required Materials:** * 1 x Black and Decker 20V Max Lithium Battery and Charger * 1 x Buck Converter * 2 x Fans (blower fans) * 1 x MERV-13 Air Filter * 1 x Solid core copper wire (20 AWG or higher) * Hot glue or sealant/adhesive of choice * Sealant/solder for electrical connections * Wire crimpers and terminal connectors **Step-by-Step Instructions:** 1. Review all posted GIFs, photos, and attached files to understand the design. 2. Obtain all necessary materials listed above. 3. Print all STL files provided (housing, gaskets, lid, locking key, and battery mount). 4. Assemble the housing by attaching the fans, buck converter, and sealant/adhesive as required. 5. Connect the wires to the terminals and buck converter using solder or hot glue. 6. Test the PAPR with a fully charged battery to ensure proper function. 7. Cut out the filter patch from the MERV-13 air filter using scissors or a knife. 8. Place the filter patch over the housing, securing it with the gaskets. 9. Attach the lid to the housing using the locking key. 10. To use the completed PAPR, slide a fully charged battery onto the adapter and attach to a CPAP tube and mask. **Important Notes:** * This design has not been certified or professionally tested, so use at your own risk. * Please post comments and questions as they are vital to developing this device. * Donations are greatly appreciated and will be used to further support this device.
