***Update 4/19/2019 - Added a remix of Tim Osullivan's throat valve (Credit to Tim for the original model) ***Update 10/10/2018 - Added STLs for the front and back chest pieces cut in half for those not keen with Meshmixer or Netfabb ***Update 8/06/2018 - The previous version had the side bolts mirrored left to right. This was not correct. The right bolt goes into the front chest half whereas the left bolt goes into the back chest half. I updated the front and back halves of the chest for the correct placement of the right side bolt and moved the inside lip on the right side to the back half of the chest. ***Update 7/28/2018 - Added new revision of the belly circle to include the thin outer ring that was missing. These were modeled from scratch using Blender and Autocad. Reference mainly taken from 3D scans of the Don Post statue by TheHappyOne and photos from TK409 and MrTea's reference libraries online. I have not printed them. If you do, please provide feedback and post. Wall thickness is mostly 3mm. These will be able to be assembled and glued together to make a complete front and back assembly and shoulder assemblies. I included small alignment holes in each part. The holes are modeled 1.75mm in diameter so you can use printer filament if you want. You may want to use small screws instead of glue on the pistons, back panel and neck rings so you can take them on and off. If so, you can drill out the small holes for whatever sized screws that will work (probably #4 screws). Just be careful when drilling. I drill by hand (without power tools) to keep from splitting parts. I included a lip on the seam edge of the chest front to align and support the back of the chest. There is a small hole through this lip and the back chest part in the location that the side button goes. The side button is the same as the one on the shorts so I did not include it here again. I did not model the throat valve because a good model is already available on thingiverse. For the throat valve, a large hole can be cut into the front shell using the small hole as a center guide. This can allow you to insert the whole throat valve into the larger hole. Alternatively, you can print the throat valve shallower and just glue it directly on top of the front shell. The shoulder bearings are intended to be glued directly onto the shoulder bells. Only one shoulder is uploaded. You can mirror it for the other side. I wished I could have designed fully functioning shoulders with ball bearings and hinges, but I decided to simplify the design for the time being. I may revisit the shoulders after I have completed the remainder of the parts. One thing I noticed when modeling this is that the overall scale of the Don Post model is definitely smaller than real life. I will continue to model all my parts to this scale but I recommend you take measurements of yourself or other purchased parts you have and choose a scale to print appropriately.
