⚠️ SAFETY DISCLAIMER & LIABILITY WARNING ⚠️ READ BEFORE PRINTING OR USING: This model is designed strictly for INDIRECT projection viewing. Under no circumstances should you or anyone else look directly at the sun through this tube, through the pinhole, or outside of the tube. By downloading, printing, and using this model, you acknowledge and agree that you are doing so at your own risk. The creator of this 3D model assumes zero responsibility and no liability for any eye damage, personal injury, equipment damage, or accidents resulting from the printing, assembly, use, or misuse of this device. Adult supervision is absolutely required at all times when using this around children. You can just copy and paste that block directly above the "About This Project" section in the template I gave you earlier. It protects you and makes sure other parents take the safety instructions seriously!   This is a Eclipse projector uising a holder for a GoPro Tripod adpted from https://makerworld.com/en/models/792814-leyzne-to-gopro-direct-mount-v1?from=search#profileId-731437   I designed this projector tube so my family—especially my 4-year-old—could safely watch a solar eclipse without any risk of looking directly at the sun. Standard eclipse glasses can be tricky for young kids to keep on, and looking up at the sky can be dangerous if they slip. This tube acts as an indirect pinhole projector. It mounts directly to any standard GoPro tripod and projects a crisp, inverted crescent shadow of the eclipsed sun safely onto a piece of white paper on the ground or a table. Everyone can gather around and watch together! How to Use It (The Shadow Alignment Trick) Mount the tube to a standard GoPro tripod. Place a piece of white paper on the ground or a table beneath it. NEVER look through the tube at the sun. To aim it, watch the shadow the tube casts on your paper. Adjust the tripod until the tube's shadow becomes a perfect, tiny circle. Once aligned, a bright image of the eclipsed sun will shine through the center of the shadow! Crucial Print Settings (Please Read!) To make sure the projector works safely and doesn't let stray light wash out the image, you must follow these settings: Filament Color: You MUST use Black filament (Black PLA or PETG). White or light-colored filaments are translucent and will let ambient sunlight bleed through the tube, ruining the projection. Walls: Set Wall Loops to at least 3 or 4 to ensure the tube is 100% opaque. No Vase Mode: Do not print in Spiral Vase Mode. The walls will be too thin to block the sun, and the GoPro prongs will print hollow and break. The Pinhole: The model features a 1.5 mm pinhole at the front. If your slicer tries to close it, or if it strings during printing, just poke a hot sewing needle through the center to clear it.   Hardware Required 1x Standard GoPro Thumbscrew Any GoPro-compatible tripod or handle
