This very cheap cost only 10$ ! If u want a metal helicoidal focuser cost only 40$ !. Instruction: 1) mount the lens in the "lens_hold.stl" and block with "lens_lock.stl". U don't need glue; 2) using glue fix "lens_hold.stl" in "central_piece.stl" and after "central_piece.stl" in "fok_side.stl". If u want use in visual with a plossy probably u need of 10mm T2 extender. If u want use like guide scope with a mini cam u need of 35 T2 extender. If u want u can print mine helicoilad focuser project rather than buying it > https://www.thingiverse.com/thing:4695777 U need 2x M5x35 and 2xM5 nuts to complete.
