WORK IN PROGRESS All systems functioning, minor adjustments required. I'm currently refining each component in question: Front Clasp (Tolerances need improvement, print from bottom to top for optimal results) Top Half (This is a challenging print, I'm working on optimizing it for higher success rates) *** Aka the T.U.S.H. - CAN V1 Totally Unmatched Superiority Holder - Container Version 1 Fits spools up to 75mm thick & 210mm wide in diameter Provides precise temperature, humidity, and weight readings in grams. Leds: Red indicates 0-250g remaining Yellow signals 250-500g remaining Green shows 500-750g remaining Blue warns of 750-1000g remaining Pulsing alerts to high humidity levels Print settings: 0.4 Nozzle; 0.3mm Layer Height; 3 Shells 10% infill for the two frames. 25% infill for roller, clasps, and hinges. BOM: Materials: ~900g of your chosen filament (PLA, ABS, or PETG) for frame, clasps, and roller ~100g of flexible TPU/TPE for seal Acrylic or clear plastic sheet for windows Hot Glue for sealing windows Hardware: 32x M3 Bolts / 24x M3 Nuts 2x M5 Bolts 2x M4 Bolts 1x 8mm Threaded Rod (for hinges, double-clasp if no hinge available) 2x 10mm Threaded Bowden Coupler 1x Eva-Dry 333 or Desiccant Packets Electronics: 1x Arduino UNO 1x DHT11 - Temperature & Humidity Sensor 1x HX711 & 1x LoadCell - Weight Sensor & Amplifier (requires a specific 5kg loadcell) 1x 16X2 1602A LCD 4x WS2812B - Addressable LEDs (optional, adds extra time and cost) GITHUB PAGE TO CODE COMING SOON Accuracy and functionality are my top priorities. I'm not a professional engineer or programmer, so some design decisions may raise eyebrows. This project was a personal challenge to utilize spare parts, learn CAD & CODE, and give back to the open source community. Temperature and humidity readings are as accurate as the DHT11 module allows. With careful wiring and HX711 calibration, you can achieve precise weight readings. Assuming proper setup, I estimate an error of ~1-2.5 grams. Rushing or poor connections may introduce noise, increasing the error to around 10g. Moisture protection? It's too early to say, as this is my first print. While not airtight, it should be better than leaving it exposed. This project was about the overall package, not just moisture control. Future improvements: Windowless version Platform compatibility for various load cells Segmented parts for smaller printers Special thanks to everyone who helped me on this project and to the open source community!
