It was a pretty easy print. The layer lines are a bit rough; I don't think I was paying attention when I sliced it and accidentally set it at my default 0.28mm for my "structural" and household prints, instead of the finer 0.20mm. But hey, it works. ;-) I printed the hollow version to allow for the future inclusion of electronics and LEDs. My plan involves using an Arduino Nano BLE 33 and some small flat LED diodes. The Nano 33 will enable me to power the Nano and LEDs with a couple of AAAA or 2032 batteries. I'll need to drill a few holes in the hinge area for wire pass-through into each section, which isn't a big issue. However, this could be a future improvement suggestion for the creator. This modification can also be achieved with almost all slicers out there, by using a negative cylinder part modifier. For the graphics, I used my Cricut Explore Air 2 and Cricut Design Space. As I mentioned in an earlier comment, the graphic should be 65mm in width, which fits perfectly. I used plain paper and covered the paper with some clear SLA UV resin cured with a UV flashlight. Protects the paper yet still allows the LEDs to shine through. However, for durability, you can use clear adhesive labels suitable for laser printers and then adhere them to a thin plastic sheet, which can be cut by the Cricut. My Cricut project can be found here: [Cricut Design Project](https://design.cricut.com/landing/project-detail/657c94512357c440b79a19e3) For the electronics, I plan on using the following components: - Arduino Nano 33 BLE: [AliExpress Link](https://www.aliexpress.us/item/3256805931036112.html?spm=a2g0o.cart.0.0.428738daFfB6dQ&mp=1&gatewayAdapt=glo2usa) - Various colored LEDs: [AliExpress Link](https://www.aliexpress.us/item/2251832633262678.html?spm=a2g0o.cart.0.0.428738daFfB6dQ&mp=1&gatewayAdapt=glo2usa) - AAAA Batteries: [Amazon Link](https://www.amazon.com/gp/product/B000UUMQKW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1) (Yes, four A's! They are smaller than AAA but still 1.5V) I used tree supports, so the interior is rough, but they were easy to remove! I aslo used BambuLabs breakaway support filament for PLA making removal even easier. I was having trouble with the provided printed hinges. I used some metal hinges I had for my laser cut boxes and the flat portion of the printed hinges as spaces to get a good fit for the small metal hingegs. I would reccommend getting some metal hinges if you want to be able to handle or use the TriCorder as a Prop for CosPlay.
