Beep Boop Beep! Accessorize your Amazon Echo Dot Version 2 with R2D2! (check our other listings for the Version 3) A perfect item for any Star Wars fan, this made to order accessory is 3D printed with PLA on an FDM 3D printer. What that means is thin layers of plastic are built up slowly to form the product — the layer lines are visible if you zoom in on the pictures. Since each print is done one at a time, each item is subject to some imperfections and differences from one to another. The interior surfaces will have a rougher finish but will be hidden when placed on the Echo Dot. After printing, I lightly sand, paint and assemble each item before shipping. This accessory is made for the 2nd generation Echo Dot and if you're unsure of what version you have, the 3rd generation has fabric around its body where the 2nd gen is all plastic. Both the 2nd and 3rd gen have 4 buttons on its face but the 1st gen just has 2. If there are any questions feel free to send me a note. Also, if there are any issues with your order please contact me before leaving a review, I am more than willing to resolve any problems that may come up. PLA (Polylactic Acid) is a biodegradable plastic made from sugar cane or corn starch. It is susceptible to heat and will warp if left in a hot car or direct sunlight. Amazon Echo Dot is NOT included.
