Spooly (Drill compatible Kite spool)

Tired of winding up your kite string?! Say hello to Spooly this design allows you to wind up your kite spool in less than a minute by using a device most people already have at home (An electric drill). Simply plug Spooly's axle into your drill and pull the trigger
Some assembly required and parts to order, a quarter inch diamter aluminum rod(foot long). And 4 screws and 4 nuts from McMaster see part numbers here 94855A281 and 92196A110. The final parts you need to order are bearings, two bearings with part number 57155K377 are needed. In the design I made I made the middle section and brakes from a wooden dowel because I made it as a design for a class and they gave us a budget and inflated the price of 3D printing unfortunately so we had to use wood to save on theoretical cost. Also, in the project we laser cut the guards. However, they can all be printed and should still work well. If you have questions about assembly ask in the comments and I will do my best to help out.
This is for the design challenge and the Theme is Summer.
