Panzerhund Robot Attack Dog

Wanted a big Panzerhund like in the Wolfenstein games, the original model form the game was a bit complicated so I designed my own. Just think of it as a prototype to the ones in the game.

I'm still in the process of printing this so some things may change.

1/14/2018: Left out a socket, instructions to come once I finish the printing
1/15/2018: I feel pretty confident no changes will be needed so added the Fusion360 backup file.
1/16/2018: Neck Socket was not modeled correctly, uploaded a new version, fusion backup file is not up to date at this time.
1/16/2018: The socket inserts on the leg joints were a bit weak so I have increased the base size.
1/18/2018: Completed most of the printing, turned out good except the leg joints are too loose to support the weight. I think in a redesign in the future I will move to using hardware to connect the legs together so that tension on the joint can be adjusted.

1/28/2018: Late update, work has ben busy, new leg joint design finished, going to be testing it soon. It will use rubber washers and screw compression to add resistance. V2 has been added, though it has not been tested yet, so things may change.

1/29/2018: Fixed the Joint length, printing a test of the joint tonight, so please hang in there, V1 is still available as a zip file acrhive.

2/19/2018: Test Printing the front legs with the new joints, the rubber for the washer I am using is:

2/20/2018: Updated Lock for joint, also added a B and C version, each with 1 and 2mm depth increase for more locking. Added O-ring for external compression, type 110 3/32, 3/8" ID 9/16" OD. Details on drawing. Assembly drawings for Panzerhund coming soon. Locking joints work well, as seen in picture, moving on to Neck joint next, then body V2 for more sleek look.

2/22/2018: Uploaded new version of neck, lower/upper jaw, and body. (lock for body to neck joint is coming in the next day)

3/16/2018: Working on finishing the new design print, the neck had some dimensional errors that have been fixed, hopefully get drawings done soon.

3/27/2018: Finished the build, every looks nice, added a few variants of the rear body peg (10mm, 10.4mm, 10.8mm)

4/1/2019: Added missing rear body
4/3/2019: Added missing rear mid leg piece

7/17/2019: Added head/neck simple assembly drawing
