Halo 4 Helmet Full Size A

cults3d

All designed in Autodesk Fusion 360 Note ChinFront_r1_0.stl has been updated to address artifact present in Makerware. Not apparent why, but single slice layer was appearing as just support near top of print. Piece flipped in netfabb and resaved, artifact goes away! All STL sliced with Makerware to x3g at medium profile 0.2mm layers, default settings, 2 shells, 10% infill, with raft and support. Latest Makerware suggests scaling some pieces to fit. DO NOT. All pieces will fit a Replicator 2 print area with simple rotation about the vertical axis and centering. The "down" face should be preserved for best results. Total build time for main body is ~60 hours on my Makerbot Replicator 2 in PLA. Including pins ( no visor or magnets ) is 680 grams, so you can budget one Kilo gram per helmet with raft, support and reprints. Don't forget some natural for your visor / inserts. Its 16 main pieces as per attached files, and 4 inserts / visor. Using the other "things" for combined pieces it comes down to 12 main pieces. You can get it down to 7 main + insert full plates by printing multiple pieces on one replicator 2 bed. All uploaded files have been preprocessed in netfabb basic for integrity and orientation.

Magnet for snap attach of peak, chin and visor if desired. Add foam to fit for proper alignment. Use 5mm LED's in all inserts. - 6 off ( presently ) Assembly order is roughly shown at https://hackaday.io/project/254-halo-4-helmet-size-a-b-c/log/31656-assembly-order No grunts were spared in the making of this product. Enjoy. This is a 15% reduction of the 6'6 model. So scaled to 85%. There are many other changes so not all parts can be reversed back into the 6'6 model., however, should you wish to try for parts like the vacform mold, chin piece with detail, or the hex visor, you would scale the A size model pieces by 117.6471%
