My part snapping code tries to pull parts together. So when you want to insert a part and it connects to something in the scene it pulls the to be inserted one so the target's y-axis' so they align.
For the three way connector parts 10288 and 57585 this goes visually wrong for some axles because both have rounding errors so even over 20LDU they end up about 1 deg crooked.
