thingiverse

Used oven converted into drying filament dispenser. Loaded with ceramic tile for safety and thermal insulation. Consumes ~ 7W power in steady state at 50°C inside and 25°C outside. Temperature range for continuous 24/7 operation: * PLA: 50°C - safe; 55°C - starts to stick; 60°C - spool fuses in 1 day * Nylon: 50°C - safe; 95°C - safe, dries 4x faster, consumes 3x more power; * therefore use same temperature of 50°C for all filament types, maintenance-free Example usage with nylon which was initially stored at 25°C and 40% humidity: * criterion: from visible bubbles in the print to no steam bubbles in the print * 3-4 outer-most layers become dry in 4-5 hours at 50°C, need to wait * inner layers dry continuously during print, no need to wait * 1kg spool full drying time is about 10 days at 50°C Parts: * 1 x [used oven](http://kitchen.manualsonline.com/manuals/mfg/hamilton_beach/31160.html) with ~ 8Hx10Dx12L" inner space * 8 x [4x4" ceramic tile](https://www.menards.com/main/flooring-rugs/tile-stone/ceramic-tile/c-6547.htm?Spec_ProductType_facet=Tiles&Spec_ApproximateSize_facet=4%22+x+4%22&ipp=28&sortby=priceAsc) on the sides * 4 x [6x6" ceramic tile](https://www.menards.com/main/flooring-rugs/tile-stone/ceramic-tile/c-6547.htm?Spec_ApproximateSize_facet=6%22+x+6%22&ipp=28&sortby=priceAsc&Spec_ProductType_facet=Tiles) in the back * 6 x [9x12" ceramic tile](https://www.menards.com/main/flooring-rugs/tile-stone/ceramic-tile/c-6547.htm?Spec_ProductType_facet=Tiles&Spec_ApproximateSize_facet=9%22+x+12%22&ipp=28&sortby=priceAsc) on top and bottom * 1 x [PC4-M6 socket](https://www.aliexpress.com/wholesale?SearchText=pc4-m6) on a side * 1 x [PTFE guide](https://www.aliexpress.com/wholesale?SearchText=4mm+ptfe) inside Used with: * [Turntable: Spool Plate](https://www.thingiverse.com/thing:2520275) * [Hanger: Thermometer Bracket](https://www.thingiverse.com/thing:2520222)
