About this 3D model

Heres my first print on my new printer (needs some tuning) and also my first designed model. I made this because I couldnt find any decent cheap holographic sights for airsoft and didnt want to spend $60+ on a sight i may never use. This sight is also RIS rail ready and even on my un-tuned printer, it didnt need supports for the top of the sight, nor the rail canal thing. I did however use a Brim due to my heated bed being broken as a precaution. Please excuse the rough images, I'm going to clean the print up a bit and paint it, then I should update them soon. ^~^
