This is a multi-part version of Mjolnir based on the design used in the Marvel Cinematic Universe. It was designed in Fusion 360.
This is the parts list:
Hammer:
1x HammerBot.stl
1x HammerTop.stl
2x HammerEnd.stl
1x HammerCap.stl
4x Core Connectors
Each core connector has its clearance measurement in the file name. On my Prusa Mk3s, the .2mm works best.
8x Details
Both loose and tight detail files are included. I would recommend printing one of each and testing them for fit then printing more of whichever worked best.
Handle:
1x HandleBot.stl
1x HandleMid.stl
1x HandleTop.stl
This design also uses a 370mm x 3/4" wooden dowel rod to provide additional strength to the print. The handle parts also have registration pins for pieces of 1.75mm filament to keep them lined up.
I used 3D Gloop to assemble the entire design but any glue should work.
