Over the last few months I have has some major setbacks on the BMP-11 project. I printed the pistol grip area with partial success.
There was horrible warping and some poorly adhered layers causing the part to be pretty fragile. The trigger guard broke with just a bit on handling. This was printed with 80% infill and took 22 hours to print. It did prove that a shape can be printed with success and I was starting to think I would have to cast the parts. I also let a number of people hold the part and the conclusion was the grip was not comfortable.
I then redesigned the 3d model to have a thinner grip and more room for the web of your hand.
At this point I gave up for now. I started reading up on California SB374, the new Assault Weapon Ban and decided to put this project on hold. It turns out the new ban will not affect M11 type guns, but I have dozens of other kits that will need to get finished by Jan 2014. I can get back to the BPM-11 at a later time.
