Junction box extension ring for boxes with screwholes 60mm There are some available but mostly in 1 or 2 sizes. So decided to make one myself I can adjust to desired size. Sizes inlcuded are 12 - 16 - 20 - 24 mm. Adjustable to your own needed length. --> UPDATE 1: New STL files because there were some faces inverted which gave some problems with slicing. Also changed the orientation of the files for easy drag and drop -->> UPDATE 2: New STL files / found out that the orientation of screwing holes was in wrong place. Switched positions. Should be fine now. -->>> UPDATE 3: Adjusted screwholes after testing, they were too tight, also adjusted the insert part (-2mm) to save material -->>>> UPDATE 4: Adjusted and refined the thicknesses on screwholes after finding a problem with inserting the sockets. Added more sizes in steps of 2mm. Also renamed to have better readability on printer screen.
