I bought a laser tube replacement:
problem is my new tube diameter is 55mm while the old tube (now that I measured it) is 50mm - didn’t know they sold different diameters as I didn’t have a choice when buying.
Now that I got it, it won’t fit in the old clamps, can I hold it down with zip ties or something? Does it really need to be clamped down?
Advise and help needed please!
