PCB Drill

Hi guys
First of all I want to apologize for my English, so if I made some terrible mistakes or something doesn`t make sense please let me know:)

This is the PCB mini drill. It`s my first design so if you come across some problems feel free to contact me or leave a comment. Also I am sharing my SolidWorks 2014 files so if you want you can make changes to model of your own. The motor holder part is designed to be removable, so it can be redesigned to hold another type of the motor.

The following hardware will be needed to assemble the drill:

M8 (13mm) nut
M8 x 130mm threaded rod (1x)
8 x 150mm rod (2x)
6 x 70mm rod (1x)
6 x 100mm rod (1x)
Spring (1x)

Motor (39mm in height, 29mm in diameter) , or some other but the motor holder part must be changed to fit different motor ( You can find these motors in some old printers )
