Y Belt Tensioner - LONGER LK4 PRO
thingiverse
This is a remix of the x axis belt tensioner for alfawise u30. I really liked the design so I modified it to y belt tensioner. I designed and tested it on Longer LK4 Pro, so I don't know if could work on basic LK4 or alfawise brand (maybe try and let know in the comments). It need a little bolt (diameter 4, 30 mm long) and a nut to replace the original one. If you haven't got, you could print something similar ;) I hope you like and find useful my work! Good Prints! PS. pay attention not to tend too much your belt becouse it will break! I lubricated with a bit of vaseline to make movement smoother, but I think it could work also without it.
