Logic Masters Deutschland e.V.

This puzzle was set for round 1 of the first Skunkworks League competition season hosted by @damasosos, in which participants get a few weeks to set a puzzle per round. For this round, the lines and inside of the grid were given, and participants were forbidden from modifying the interior of the grid (other than given digits) as well as placing any extra lines.

Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
Some lines have been given, draw some more lines of length 3 such that no line overlaps with another and each line is cloned by at least one other line of the same shape (the same digits repeat on a clone in the same order and without rotation).
Each line contains at least one digit equal to the distance to its clone (the distance is the minimum number of orthogonal steps necessary to get from a cell on a line to the corresponding cell on it's clone).
