# The FinnBox Some facts: ** espuino based: https://forum.espuino.de/ ** The box uses 5 touch sensors (TTP223). The only physical push button is on the back for power on/off. ## **Printer Settings:** #### box_bottom & top, speaker grid, speaker devider: - no rafts, no supports, 100% infill, 6 wall lines, .2 resolution #### mounting bracket: - supports active but blocked for the inside of speaker and espuino attachments, basically everywhere where we want to put in brass threaded inserts later I put a support blocker. ## Used Material: - [Wemos Lolin D32 Pro v2.0.0 (16mb)](https://de.aliexpress.com/item/32883116057.html?spm=a2g0o.productlist.main.1.1436bde9r4BqIq&algo_pvid=738235c7-225b-4cba-b3e2-18f5f56808eb&algo_exp_id=738235c7-225b-4cba-b3e2-18f5f56808eb-0&pdp_ext_f=%7B%22sku_id%22%3A%2267195983692%22%7D&pdp_npi=3%40dis%21EUR%2111.52%2111.52%21%21%21%21%21%40212244c416786947923968709d0728%2167195983692%21sea%21DE%212331545212&curPageLogUid=ICZJCfQ8w3zE) - ESPuino PCB - [PN5180](https://de.aliexpress.com/item/4001090434312.html?spm=a2g0o.order_list.order_list_main.5.21ef5c5fcsuYKt&gatewayAdapt=glo2deu) - [EREMIT Lithium Polymer LiPo 5000mAh 3.7V](https://www.eremit.de/) - [Visaton FR 10](https://www.amazon.de/gp/product/B003NT6YNM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - [Delock Panel Mount USB 2.0 Micro-B > USB 2.0 Micro-B 25 cm](https://www.amazon.de/gp/product/B0754MNQPN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - for version with Micro-USB (**box_bottom.stl**) - [CY Panel Mount USB-C USB 3.1 Typ-C 20 cm](https://www.amazon.de/gp/product/B075R7QBQD/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - for version with USB-C (**box_bottom_usb-c.stl**) - [TTP223 Capacitive Touch Switch Button Self-Lock Capacitive Switches](https://www.amazon.de/gp/product/B07WH722L1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - [WS2812 RGB LED Ring (24 LEDS)](https://www.amazon.de/gp/product/B08GYVFKLT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - [Metzer pushbutton Ø 19 mm](https://www.amazon.de/gp/product/B079Y62LRB/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1) - [Metal Plates](https://www.amazon.de/dp/B09JC9YS87?ref_=cm_sw_r_apin_dp_4TJFJ1SBPQK0EPV8CEC0&th=1) - [M2, M2,5 screws](https://www.amazon.de/gp/product/B09GXPLHL4/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1) - [threaded brass inserts](https://www.amazon.de/gp/product/B09B7F2XM3/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1) ## **Remarks:** #### LED RING There are 24 LED rings with different diameters. The measurements for the LED ring that I used are: - Inner Diameter 74mm - Outer Diameter: 90mm The ring with these measurements will fit into the **speaker_grid.stl**. There are also rings with smaller diameters. I made one for a 24 LED ring with an inner diameter of 72 mm. For this please use **speaker_grid_72mm_led.stl** #### HEADPHONE PCBs Since there are different [revisions](https://forum.espuino.de/t/kopfhoererplatine-basierend-auf-ms6324-und-tda1308/1099) of the headphone PCB there are also different top cases for the Finn box. - **box_top.stl**: This is for the old PCB using UDA1334 - **box_top_new_headphone_pcb_ms6324.stl**: This is for the most recent headphone PCB using the MS6324 #### LiFePo4 Battery The box was originally designed to include a flat LiPo battery in the middle. There have been requests as well to support a LiFePo4 battery which has some advantages compared to the LiPo chemistry. The Finnbox is quite small so to find room for a [3.2V 6Ah LiFePo4 battery](https://www.eremit.de/p/3-2v-6000mah-pack-mit-schutz-arduino-aio-spezial-jst-ph-2-0-stecker) was difficult. However I created an experimental version that should support this battery. **box_bottom_usb-c_eremit_LiFePo4.stl**
