This is the parts list for the Grove GMK6400 MKIII Carrier only (no superstructure, no boom). This is the "second" version of the carrier, which does not use shock absorbers and has several reliability improvements to the original suspended version. The zipped PDF instructions (of the carrier, superstructure with firgelli actuators, and boom) can be downloaded here

Since there are several variations of the superstructure, I've uploaded the parts list of just the carrier here to make it easier to see which parts you need for the superstructure of your choice. This is not my MOC! This MOC is a community project and credits should go to Gerger, Blakbird, AFOL1969, (and others) for the design and the detailed instructions. Refer to the eurobricks thread for this MOC here

There are multiple choices of superstructure and boom to build, and the parts for those are not included here.
- With firgelli linear actuators.
- With standard lego linear actuators.
- With custom built linear actuator ouf of lego.
- With 3D printed linear actuator.

All of the above superstructures should fit the same carrier assembly.

The parts list for the entire GMK6400-MKIII (carrier, superstructure, boom) using firgelli linear actuators is here

You can reference the additional parts needed for the superstructure and boom of the GMK 6400 MK III with firgelli linear actuators here
