Shift boot ring for Cobalt/G5

This is a shift boot retainer for the Chevrolet Cobalt and Pontiac G5 that use the Getrag F23 designed using a part from the junkyard.  the fit is not perfect but i have been using it in my car for 6 months at the time of upload. 
 

Print in abs or ASA, PLA and PETG will melt in the car so i do not recommend using it

the spring tabs at the front are a little fragile but the outer ring at the top has been reinforced 

drilling holes for the staples may be required if you plan on stapling your shift boot to the ring, however i have found a friction fit should be more than enough.

If this ends up working for the Chevy HHR or similar sister vehicles to the cobalt please let me know so i can update it 

will NOT Fit:
Cobalt SS Supercharged, Cobalt SS Turbocharged, HHR SS Turbocharged 
reason: design differences to accommodate the reverse lockout requiring different shape shifter cutout. I will be designing a model for those vehicles in the near future.
