Hunchback BattleMech 3D Printing Files | Assembly + Action

There are lots of awesome Mechs in MechWarrior online universe. Hunchback BattleMech 3D Printing Miniature is inspired by one of them. Of course, it is smaller than its prototype, but still fascinating. 

50 tons of metal, starshield armor, a huge riffle on a shoulder - Hunchback looks really dangerous. And not only looks so - his technical characteristics and striking power are impressive. One of the most feared mechs in a history, his armoring is really outstanding. As a main weapon it uses Tomodzuru Autocannon Mount Type 20 - a direct-fire autocannon, which can blow away more than a ton of armor in one moment. It also has two Ichiba 2000 Medium Lasers in his hands and a small optic laser launched in his head.

Both FDM and SLS/SLA versions are available. The real size of Hunchback is considered to be 13,5m.

FDM version:

• Is 1:60 scale and after being printed will stand 225mm high, 140mm wide, 107mm deep.
• Is designed to save almost all movable elements its prototype has;
• Has removable hinges that should be printed with 100% infill to make them solid.

SLS/SLA version:

• Is 1:100 scale and will stand 135mm high, 95mm wide, 67mm deep.
• Has as little details as possible to keep printing budget about 50-60 $.

On 27.10.2017 new version of joints have been added.

To use new joints, you do not need to reprint the whole model of your Mech!
You can find detailed picture guidelines about how to use new joints in your model HERE.

With the new joints you will get next advantages:

1. Increases frictional force
2. Possible to up scale or down scale the whole model
3. Printable from any type of material
4. Higher strength
5. Material shrinkage does not affect at strength and friction

STL files are already available for download in “Source files” tab for Version 1 (FDM/FFF 3D printers). You can find them at the end of the list.

Generic

This model was tested in Cura 2.7.0. and print on an Ultimaker 2 in PLA material.

Note:

- You can print new joints with 20-30% infill. 
- With the new joints you can up scale or down scale the whole model.

- You should print old joints with 100% infill. 
- With the old joints do not try to up scale or down scale the whole model since it will not be assemble or movable after scale changes.
- Using the PLA material you should increase the scale of old joints at 2-3% in your slicing program.
- Using the ABS/CPE material you should increase the scale of old joints at 1% in your slicing program.
