Plan Your Build & Get Hardware

ExoGuitar can be confusing! Head over to our build planner to plan your entire build - it'll walk you through every available part and handle compatibility along the way, and it covers all ExoGuitar parts. It's also the best way to get hardware, since it lets you buy everything for a full build in one go, not just this part.

You can find this specific part, ExoGuitar - Head - Classical, on our site.

After printing, make sure you clean out ALL support material. The smallest amount in the gearboxes can cause interference, the tollerances are very tight.

Step 1: Put in Heat Set Inserts

Step 2: Put in Bearings

Step 3: Assemble 6 Tensioners

Step 3a: Cut TPU Filament Stubs

Cut 6x 5mm long pieces of TPU filament. A model for a jig to cut these to size easily is included here

Step 3b: Assemble Shaft

Note that the TPU filament piece is inserted BEFORE the heat set insert is installed.

Step 3e: Prep Worm gear

Using a 3/32 drill bit, remove 3mm of material from one side of the worm gear hole. Then install the heat set insert into that hole. BE CAREFUL and make sure you go in straight and that you don't melt the gear teeth.

Step 3f: Assemble Knob

The screw should go right up to the end of the worm gear but not stick out of it.
Use locktite or super glue to lock the screw into the gear. I recommend Locktite Red

Step 3r: Install Tensioners

Step 3f: Lubricate gears with Synthetic Grease

Step 4: Install Side Panels

Step 5: Put in all the screws!
