Description

This BMW tweeter has been carefully measured for almost 4 months for a temporal contract now feel free to use, modify and customize, but keeping it open source, the logo on the back can be remove its a touch of my personality but as I said you can change it to anything I tried a ton of different filaments, the cheapest and with an extra property is ASA with the UV degradation resistance, can be printed on FDM, or resin with more durable materials. DON'T use PLA, PLA+, any PET, TPU, or materials with a malleable temperature below 70ºC or 158ºF they will warp and a lot, here in chile 28ºc outside with leather seats can warp PETG in 2 hours, I tested ASA for 8 hours straight and 32ºC and nothing.
