### Laboratory equipment for teaching STEM in schools PART 8 ### sm_pb 07/2019 thing:3761008 I have developed a tripod system for teaching STEM 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 some components i needed to realize the famous experiment of the laser interference by gratings. <b> 18_mount_for_screen_NEW: </b> 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. <b> Information: I have improved this mount. So please use the "NEW" file now. </b> <b> 19_mount_for_slide_frames </b>: 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. <b> 20_mount_for_laser </b>: 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
