I made this design inspired by the original design of the Creality lamps, it seems to me that I could use an aluminum U-shaped rail, just print the edges, this design is very easy to do, it does not require supports and you will have enough tolerance margin for your printer model, you can also modify the file yourself, if you have any problem with the design write me at jonn29.jp@gmail.com or pro WhatsApp at +50766411028 I will gladly help you greetings from Panama
