2
+ * Based on "Y-Axis Bracket" by "daveth26":
3
+ * http://www.thingiverse.com/thing:1104535
4
+ *
5
+ * Recreated and modified by:

+ * Thomas Buck <xythobuz@xythobuz.de> in March 2016

9
+ *
10
+ * This part has been modified to use a 25mm fan instead of 
11
+ * a 30mm fan. This can be set in the parameters, but beware
12
+ * of any problems, I have not tested any other sizes.
13
+ *
14
+ * The Fabrikator Mini V1.5 include a new bracket that prevents
15
+ * the old design from sliding fully onto the stepper motor.
16
+ * A parameter has been added (fab_mini_v15) that allows
17
+ * reverting to the old behvior.
18
+ *
19
+ * For V1.5, a height of 25mm is suggested, as this provides
20
+ * enough stability with the big cut-out. To revert to something
21
+ * like the original model, set the height to 15mm (and
22
+ * fab_mini_v15 to "false").
