+## What I did in Week5
 
-## Code Example
+1. Test the 3D Printer : Angle, Overhang, Bridge, Wall-thickness, hole test  → In this page
+2. Design and 3D print an object  → [individual page](https://fabacademy.org/2022/labs/kannai/students/yukiya-yamane/assignments/week05/)
+3. 3D scan an object, try to prepare it for printing → [individual page](https://fabacademy.org/2022/labs/kannai/students/yukiya-yamane/assignments/week05/)
 
-Use the three backticks to separate code.
+## The 3D Printer we used :  Creality [Ender-3 V2](https://www.creality.com/goods-detail/ender-3-v2-3d-printer)
 
-```
-// the setup function runs once when you press reset or power the board
-void setup() {
-  // initialize digital pin LED_BUILTIN as an output.
-  pinMode(LED_BUILTIN, OUTPUT);
-}
+![ender_v2.jpg](../images/week05/ender_v2.jpg)
 
-// the loop function runs over and over again forever
-void loop() {
-  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
-  delay(1000);                       // wait for a second
-  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
-  delay(1000);                       // wait for a second

+**Overhang Test Conclusion:**
+
+overhang which length is under 0.2mm can be printed fine.
+
+overhang which length is over 0.3mm cannot be printed fine.

+inside dimensions : 20, 25, 30, 35, 40, 45 mm + 45, 50, 55, 60, 65, 70 mm
+
+Printed out and check wether they can be printed expextedly

+
+**Bridge Test Conclusion:**
+
+~45mm : printed very clearly just as I intended
+
+50~60mm : printed clearly to some extent
+
+65mm~ : printed bad-looking
+
+### wall_thickness Test
+

+
+![thicknesstest.jpeg](../images/week05/thicknesstest.jpeg)
+
+Conclusion:
+
+Upper row (Fence) : Shapes less than 0.4 mm thick are not output. Output is available for sizes larger than 0.5 mm.
+
+Downer row (Grooves) : grooves smaller than 0.3mm cannot be output. thicker than 0.4mm are ok

+
+Conclusion:
+
+the shape of circle (upper row) : the hole of second from left (3.1, fx : 0.05) is just-fit
+
+the shape of hexagon (lower row) : the hole of the first from left (3.0) is just-fit
