Here are some components i needed to realize the famous experiment of the laser interference by gratings.

18_mount_for_screen_NEW: This clamp makes it possible to fix screens with a thickness of 2mm (e.g., cartons), with a thickness of 3mm (e.g., plastic plates) or with a thickness of 4mm (e.g., plywood boards). No support is required for printing.
Information: I have improved this mount. So please use the "NEW" file now.

19_mount_for_slide_frames : A mount for optical components such as grids, columns, etc., which can be clamped in a slide frame typically. The fixture can be clamped in the components 08_round_table or 09_square_table (Part 3) with a little pressure. Support is required for printing.

20_mount_for_laser : A mount for a laser pointer.The fixture can be clamped in the components 08_round_table or 09_square_table (Part 3) with a little pressure. Support is required for printing.

For the components i recommend 80% infill and a layerhigh of 0.2mm
