Beginner's STEMSEL Workshop 3D Model Documentation

Transcription

1 Beginner's STEMSEL Workshop 3D Model Documentation Preface To the person who will be commencing 3D design and projects - The following models have been created by Raphael Garcia and Seth HC Yeh during the summer of Dec Feb All of the models below have been created specifically for the 10 STEMSEL BEGINNERS Workshops and are to complement the projects within those workshops. All of the models that have been created try to include each component that is used within a project to make the models more "Interactive". Whilst each model has been made to cater for each workshop, do not feel limited to only use and re-use these models. The current models here serve as a current guide of what we would like the 3D objects should be. However, if you have an idea or have a better way to show off these projects with 3D models, please feel free to create your own iteration and design. If you do create new models, document and describe them (as shown in this document) on this document. The 3D software that these models have been made in is called Sketch Up, which is a free software. We strongly recommend playing around with the program and watching a few tutorials on YouTube on its intricacies (and limitations) and get to know the softwares that are used (Sketch Up and the Up! 3D print software) before you undertake any CAD jobs. For further help, consult Matthew or Miro. Enjoy and have fun! ~ Raphael Garcia and Seth Yeh ~

2 Introduction This set of 3D prints is to be used with the STEMSEL Beginner's workshops. The list includes the following models for the 10 workshops available and the time/material taken to print each model. Project 1 Alarm System Project 2 Traffic Lights Project 3 Washing Machine Project 4 Smart Street Light Project 5 Fridge Alarm Project 6 Temperature Controller Project 7 Musical Buzzer Project 8 Smart Light Dimmer Project 9 Cool Fan Hat Project 10 Bike Indicator All of these models are available in the "Beginner's" folder that comes with this document. Each model presented is the final version of the model. Project 1 Alarm System The "Alarm System" Project works by programming the onboard button on the STEMSEL Board to activate an alarm when the button is pushed. Thus, this model works like a "Floor Trap" such that when someone or something goes on the plate/trap, the button is pushed and the alarm is then set. When using the model, place the plate into the holder with the three poles going into the three holes. The button would be then placed in the ring hole on the other side of the plate and this would create the pressure plate trap (like in Minecraft). Alarm System Approx Time: 16 Mins Material: 3.7g Project 2 Traffic Lights The Stop Light model recreates a working traffic light. The holes will be fitted with the normal Red, Yellow and Green LEDs (from top to bottom) and is used for the "Stop Light" workshop. Traffic Lights Approx Time: Material: 21 Mins 4g

3 Project 3 Washing Machine There are two versions of this model: a simple motor mount that replicates a "front loader" washing machine and a model which replicates a "top loader" washing machine. The "front loader" model works very similarly to temperature controller with mounts for LEDs on the side of the model and a potentiometer at the front. With the "top loader" model, the motor is mounted vertically with the fan facing upwards. There are holes in which LEDs and a potentiometer can be placed and it will look like a proper washing machine once it starts to work. Washing Machine (Small/Large) Approx Time: 32Mins / 1 Hour 42 Mins Material: 7.6g / 28.5g Project 4 Smart Street Light The street lamp model is to be used for the "Smart Street Lamp" Workshop. The model features a light bulb holder and an LDR holder. To use this, the wires would be placed in the centre pole of the model. The light bulb will then be placed in the holder with the bulb pointing down. The LDR will then be fitted along with the wires and placed in the centre pole. The LDR sensor should also be facing upwards to measure the ambient light. Smart Street Light Approx Time: 25 Mins Material: 5.9g Project 5 Fridge Alarm The fridge alarm works by opening a fridge and creating a buzz with a speaker when the door is left open for too long. The model comes in two sections: Door and Fridge Body. For the final model, these two parts will be printed out in one piece. There is a hole inside the fridge which is large enough to fit all of the component wires through. Fridge Alarm Approx Time: 40 Mins Material: 9.5g

4 Project 6 Temperature Controller This model works with the "Incubator" workshop which creates a temperature controller with the light bulb for heat and fan for cooling down. The motor is mounted on the four mounts. The temperature sensor is mounted through the hole above the light bulb holder. If the light bulb turns on, the close proximity of the temperature sensor will warm up the sensor. If the microchip detects that it becomes too warm, the light bulb then turns off and the fan turns on to cool down the sensor. Temperature Controller Approx Time: 44 Mins Material: 10.2g Project 7 Musical Buzzer The musical buzzer is a simple music note shaped 3D model in which a buzzer and a potentiometer can fit within the holes. It is a simple model that can be changed easily (through SketchUp) to accommodate other devices if needs be. Musical Buzzer Approx Time: 10 Mins Material: 3.7g Project 8 Smart Light Dimmer The "Smart Light Dimmer" workshop attempts to recreate a lighting system for a room; such that when the room gets enough sunlight, it can dim the lights automatically. Concurrently if the light becomes too dark, the program will turn the light even brighter. The model features a box like design to recreate a room and holes which will fit a light bulb, potentiometer and LDR. The light bulb will be pointed inwards into the room whilst the potentiometer will be facing up. This is the same for the LDR. Smart Light Dimmer Approx Time: 31 Mins Material: 9.4g

5 Project 9 Cool Fan Hat The Fan Hat practical requires a LDR to measure the current sunlight. When it becomes too bright, lights will turn on and the fan will blow into the face of the user. The model created will clip onto any hat brim. The motor will then be slid into the lower plate with the fan facing the face of the user. LED lights will be placed in the holes at the front of the model and the LDR will be mounted into the vertical hole at the top of the model. Fan Hat (Place this vertically with the front holes down and teeth up) Approx Time: 44 Mins Material: 11.1g Project 10 Bike Indicator This simple model replicates a turning indicator on a bicycle. The red LED which represents "STOP" would be placed on the middle LED holder hole and the left and right indicators will be placed in their respective holes on the indicator. Bike Indicator Approx Time: 7 Mins Material: 2g

6 Print Time and Model Details DO NOT REMOVE FROM DOCUMENT [Up! Mini 3D Printer SETTINGS for ALL BELOW] Resolution: 0.25mm Fill: MINIMAL Spacing [ icon above "Surface" ] Quality: Normal Heat Platform: 5 Mins Nozzle Height: (DO NOT CHANGE HEIGHT) Other Settings: Default Notes: To improve print time, use FAST setting in Quality or lower Resolution ( bigger than 0.25mm) For complex and intricate parts, using the Fine Quality Setting or a higher Resolution of 0.20mm will give better print results. However, it will take a longer time to print. Having a heated platform after printing allows easier removal of excess material from model When printing, orient/rotate the model around in the Up! Software to give faster print time and reduced material use. Some models will print better when oriented in a particular way. Experiment around and use the "Print Preview" menu to see which orientation will have a smaller print time/material use. ALWAYS check the printer and printing surface before start up. A well maintained printer will last a long time! ALWAYS scrape the stage/printing surface for any residual plastic from previous prints before each print job. ENSURE that the surface is smooth and clean before each print to prevent slippage and misprints. If anything does go wrong with the print job or printer and you do not know what to do, consult Miro or Matthew for help and advice. If a print job goes wrong (stops printing, runs out of plastic, model slips and gives an error print, etc) then IMMEDIATELY PRESS THE STOP PRINT BUTTON on the Up! Software located at the right hand side of the tool bars. After this, take the model out; check the print head or plastic reel for misalignment, tangles or errors and fix if necessary; remove the model from the stage and clean the stage. Check printer, plastic reel and stage before printing another job. REPORT any mishaps or accidents with the 3D printer.
