### Laboratory Equipment for Teaching STEM in Schools PART 8 ### Thing: 3761008, July 2019 I've developed a tripod system to teach STEM subjects in schools. For more information, see: Part 1: Thing 3433683 Part 2: Thing 3469091 Part 3: Thing 3469411 Part 4: Thing 3477316 Part 5: Thing 3481788 Part 6: Thing 3694510 Part 7: Thing 3761004 Here are the components needed for a famous experiment on laser interference by gratings. <b>18_mount_for_screen_NEW:</b> This clamp allows screens with a thickness of 2mm (e.g., cartons), 3mm (e.g., plastic plates) or 4mm (e.g., plywood boards) to be fixed without any support for printing. Information: I've improved this mount, so please use the "NEW" file now. <b>19_mount_for_slide_frames:</b> A mount for optical components such as grids and columns that can be clamped in a slide frame typically. The fixture can be clamped into the components 08_round_table or 09_square_table (Part 3) with little pressure, but support is required for printing. <b>20_mount_for_laser:</b> A mount for a laser pointer. The fixture can be clamped into the components 08_round_table or 09_square_table (Part 3) with little pressure, but support is required for printing. For these components, I recommend 80% infill and a layer height of 0.2mm.
