MrCool BlueTooth LED Lithophane Parts

This was an absolute blast, I utilized this site to generate my lithophane, http://3dp.rocks/lithophane/, with the attached settings altered to accommodate a maximum size of 254mm. You can find the BlueTooth LED at https://www.amazon.com/gp/product/B075RXN74D/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1. The ASIN is B075RXN74D and the Item Model Number is DT-42777. I employed PhotoShop with the following settings to create two strips that measured 53.5mm high by 301.59mm wide, separated by a 2mm gap, which perfectly accommodated the BlueTooth LED after scaling. Pixels: Width: 14248 Height: 2528 Size (mm): Width: 301.58 Height: 53.50x2+2mm Resolution: 1200 pixels per inch I printed the lithophane at a resolution of 0.1mm using Cura and a Creality CR-10s, while creating the files with AutoCAD 2015. It's essential to file down the holes for the inner top slightly to ensure a perfect fit. To remove the speaker's diffuser, heat up the top part with a hot-air blower or hair-dryer, then lift it off using a spuder tool or guitar pick and a small flat-head screwdriver. Next, snip the connecting wire that goes to the capacitive touch ring, remove four screws, and take out the diffuser. To assemble your custom cylindrical lithophane, print out the three parts I designed, place the base part at the bottom (it needs to be squeezed in a bit, but it fits and is keyed at the back), insert your lithophane, then position the inner part near the speaker (with the long skinny part facing downward), followed by the outer part. Once everything fits perfectly, glue the inner and outer top parts together, then attach them to the litho, place a couple of drops of glue on the printed bottom, and insert a few screws into the top. Allow it to set, then add more glue around the base and tighten everything (I used superglue; a 3D pen should work fine if you're patient). I employed strong double-sided tape between each screw on the top and made the strips as wide as the bottom of the speaker grill, covering the screws with a small amount of tape to prevent vibration. After soldering the wire to the touch ring, everything came together nicely. It took some time, but it was incredibly rewarding. The hardest part was drafting up the parts, aside from print time (approximately 24 hours). I'm thrilled with how it turned out! I used PLA, and while I've tested some with PETG, I still need to improve my skills with it. Edit: I added Bluetooth_Base_Holder, Bluetooth_Top_Holder, and Support_Arms (print 3) to the design. Since the BlueTooth was originally intended to be held from the bottom, I thought it would look odd with a lithophane (everything would be upside down). To address this, I designed the base/top/arms so that one could use a piece of 550 cord (slightly melt the end and press it down to flair out, then feed from the inside to the outside). Be sure to flip all the parts to print properly, as some are upside down. Additionally, I updated the litho maximum size to 254mm (I had the wrong settings from another Thingie previously).
