Small amount of movement, only a test but promising.
I thought that having a movable hinge on the front grip could result in a lot of stress on the threads that may eventually just strip out of the blaster. To fix this I have added some heat set inserts.
This gives me some nice metal threads that can't wear out. Similar to how I have added space for nylocs in the body for the "holster" bolts. In hindsight I wish I had used inserts here as well. If I have to reprint I probably will do.
I also added them to the magazine mount. I have a power switch mounted here so ease of access is important, and so is a secure fix.
These are easy to add. I just need a hole the right size added the the 3D file, I have values setup for this now. Once printed I simply drop in an insert which has a "nose" to locate it, and then use a special tip on a soldering iron set to 210C to slowly push them home.
Like all projects as I near completion on them I look back and think of all the things I would do differently if I started over and adding these more widely would be one such change.
I have some electronics parts on order, so hopefully my next update will be on that front. I also have some printer updates happening which I am hoping will release the flow on parts I need to complete the build.
Then it's "just" paint
