I printed the lamp out of pla and the top and bottom part out of petg.
I will upload a image of the lamp in the next few days
I used this lamp socket https://www.amazon.de/gp/product/B08KDS5XRX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and this cable https://www.amazon.de/gp/product/B07P91JZVY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
