### Laboratory Equipment for Teaching STEM in Schools PART3 ### sm_pb 03/2019 thing:3469411 For PART 1 see thing: 3433683 For PART 2 see thing: 3469091 I have developed a tripod system for teaching STEM in schools. In science education, all students should be able to experiment with materials as freely as possible. Therefore, this system offers many (matched) possibilities of assembly. All system parts are designed for tripod bars with a diameter of 10mm. For teaching, I recommend the purchase of rods with 750mm, 500mm, 250mm, and 125mm length. All parts are equipped with M6 screws. These are required in length 30mm, 35mm, 40mm, List of Parts / Bill of Material (BOM) 01 to 07: see PART1 and PART2 08: The Round Table: 09: The Square Table: 10a to 10c: see PART1 10d: will be presented later. 11, 11a to 11d: the Box Parts: To build a complete box, of course, eight corner pieces are needed. These corner pieces are marked for better orientation with the letters A to D. For each corner, you need three times the knob 10a 12: Flexible Construction: for these parts, I used the excellent work of Fedor Sosnin (https://www.thingiverse.com/FedorSosnin/about) and his thing:3179203 (https://www.thingiverse.com/thing:3179203). 13: Universal Plate for Electronics: A grid plate to easily attach electronic components. Drill holes are provided in three places to attach an Arduino Uno. 13_new: Universal Plate for Electronics New: Only a small improvement: now the plate is more stable, and the possibilities of attachment are increased. 14: And More... will be presented later. This project will be continued soon. ####################################################################### ### Laboratory Equipment for Teaching STEM in Schools PART3 ### sm_pb 03/2019 thing:3469411 For PART 1 see thing: 3433683 For PART 2 see thing: 3469091 I have developed a tripod system for teaching STEM in schools.

List of Parts / Bill of Material (BOM) For all parts: A support is not necessary for most parts, but this depends on the printer used. The parts 12_flex_x_male.stl and 12_flex_x_female.stl require a support. The infill should be at least 50% and up to 80%. 01 to 07: see PART1 and PART2 08: A Round Table: 09: A Square Table 10a to 10c: see PART1 10d: will be presented later. 11, 11a to 11d: Box Parts with 90° Angle for Building a Container. To build a complete box, eight such parts are needed. The parts are marked with letters A to D for easier identification. For each part, three M6x30 screws, three flat washers, and three knobs 10a are required. 12: Flexible Construction: I used the excellent work of Fedor Sosnin (https://www.thingiverse.com/FedorSosnin/about) and his thing:3179203 (https://www.thingiverse.com/thing:3179203). 13: Universal Plate for Electronic Components: This grid plate allows for easy mounting of printed circuit boards with electronic components. Drill holes are prepared at three sides to mount an Arduino Uno. 14 and More... will be presented later. This project is continuously being developed.
