### Laboratory Equipment for Teaching STEM in Schools PART 9 ### sm_pb 08/2019 thing:3793474 I have designed a tripod system for teaching STEM concepts 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 Part 8: thing 3761008 Here are some angle scale discs designed for STEM education. <b>21a, 21b, 21c, 21d, 21e Angle Scale 240mm:</b> The diameter of these discs is 240mm. Various versions are available. A hole in the center has a diameter of 10mm. The version with nine holes fits perfectly on the square table "09 Square Table" from Part 3. I suggest printing the scale with the display facing down. Support is not necessary. <b>22a, 22b, 22c, 22d, 22e Angle Scale 120mm:</b> The diameter of these discs is 120mm. Different versions are available again. A hole in the center has a diameter of 10mm. The version with five holes fits perfectly on the round table "08 Round Table" from Part 3. I suggest printing the scale with the display facing down. Support is not necessary. The print itself requires significant demands for this component, since the scale marks are only as wide as the nozzle used. It is extremely challenging to print even smaller discs. I recommend printing all components with 80% infill and a layer height of 0.2mm.
