I have yet to print this model however it is a very basic design and should work fine, it has been inspected with meshmixer and oriented properly. I will update with pictures after printing it.
Update 4/22/17: I reoriented the model for better printing and uploaded the revised version.
Update 5/13/18: I have printed 2 of this model in pla+ and it has held up great in the field for a year.
