The author remixed this model.
added sensor slot using the mount @fardog made to cut a hole in the original 285mm x 110mm x 90degree wall by @SJB4127.
i used these sensors instead of the one listed in @SJB4127's : https://www.amazon.com/dp/B07PWFDB3T?ref=ppx_yo2ov_dt_b_product_details&th=1 (non affiliate link)
