1650 case
This is the first case that I have purchased, never have used pluck foam but after reviewing videos I felt comfortable with the product. Take your time, go inititally around the perimeter and then you can plunge with your fingers. The only problem is what type of glue to use if you change you mind or make a mistake, haven't figured out what to use as a reinforcement if you want to create a lift out section for small parts. This case is being used for a telescope, telescope cavity uses both layers but lens, diagonal and other small parts use part of first layer so a reninforcement bottom for layers would be a great option.
