Echo dot && plus battery +backup

Açıklama

Sometimes one just want to travel with some gadgets to make their life easier... $;-) I came with this battery backup to unplug my echo on the go - it serves echo plus, echo dot && other 5V@2A usb hunger devices. For sure I could plug some 12V≈15V (15W) power source to this and turn it into a uninterrupted power source for any USB gadget (iPhones, iPads, androids, etc...) - but the goal here is to let echo travel without wires around home/outdoor spots. I 3D printed the .stl file on my E3D BigBox using proto-pasta HTPLA carbon fiber original, but some could do it ABS too. My printing settings (Simplify 3D): √ 15% infill; √ 0,2mm high; 2x2x2 top/botton/outline layers; √ fast honeycomb/concentric 15/35/100% interior fill/outline overlap/infill extrusion width; √ no support; √ 217º/60ºC extruder/bed; √ 2200mm/min 65/100% outline under/solid infill speed (I like it slow ≈ 5hours top); Some info available on the .pdf + BOM: √ goo.gl/vquLDm √ goo.gl/M6EE8P √ goo.gl/ByJYVs √ goo.gl/cUUKS1 √ goo.gl/xG6fDa Video: https://youtu.be/KtE0YGA0yI4 'N'Joy! $:-) .:aeronavilles:.
