 # PiZtand
-simple quick-printing configurable stand mount for Raspberry Pi Zero
+Simple, quick-printing, configurable stand mount for Raspberry Pi Zero.
 
-Also fits BannannaPi M2 Zero and Radxa Zero.
+![](PiZtand.png)
+![](PiZtand.jpg)
+![](PiZtand_rear.jpg)
 
-M2.5 screws should screw reasonably tight right in the plastic with no nuts.
+Also supports BannannaPi M2 Zero and Radxa Zero, which have components on the back side.
 
-Screw the posts to the Pi Zero, then insert into one of the sets of post holes in the base.
+## Directions
 
-Base has post holes to hold the tower vertical, or slanted at 15, 30, or 45 degrees.
+Screw the posts to the Pi Zero first, then insert into one of the sets of post holes in the base.
 
-Printing all parts at once requires 80x95mm build surface, and prints in under an hour at 0.3mm layer x 65mm/s.
+M2.5 screws should screw right into the plastic reasonably securely with no nuts needed. If the holes are too loose to hold screws, you can reduce ```screw_post_id``` from 2.5 to 2.4.
+
+The base has 4 sets of post holes at different angles from vertical to 45 degrees.
+
+Printing all parts at once only requires 80x95mm build surface, and prints in under an hour.
+
+<!--
+## Configurable options
+The scad file has several variables that you can change.
+
+```style = "thin";``` or ```"chunky"```
