Triangular Key / Triangular Key

I made a simple but effective tool to unlock bollards. I took the measurements directly from the bollards around my apartment and they are somewhat based on DIN3223. Although I can't tell for sure because I do not own an edition of the standard. Nevertheless, the tool works great, is easy to print and the handle is comfortable to hold. 

Dimensions:

• outer-diameter: 30 mm
• triangle-edge: 21 mm
• triangle-depth: 25 mm
• length: 185 mm
• handle-thickness: 10 mm
• cylinder-height: 40 mm

I used the “sky-blue” ecoPLA from 3D-Jake as filament and printed it on my A1-Mini. Feel free to give me any advice about the design/printing-profile since this is my first upload here. I would also like to know, how it worked out for you - so please drop a picture of your print (only if you feel like it, no pressure!). Thats all for now, wish you all a “happy printing”.
