I'm going to make a cardboard box tool for this video.

First, design your tool by inserting parts

and manipulating them with the select,

move, scale, and rotate tools.

You can also add color and material

in the properties panel.

Once you've created your parts,

insert one more and name it Handle

with a capital H.

Using the scale tool,

set the size of the handle to be small

and set the transparency to 1.

This part will determine where the player holds the tool.

Drag it to the bottom of the box

or wherever you want the player to hold the tool

if you are creating a different tool.

Click on the plus icon next to the workspace

and insert a tool.

Select all of your parts which you just created

and drag them inside your tool.

Then make sure the anchored property is unchecked.

We now need to weld all of the parts

so that the box does not fall apart when equipped.

Click the plus icon on the handle

and insert a WeldConstraint.

Set the Part0 property to the handle.

Set the Part1 property to one of the other parts.

Repeat this until you've set up WeldConstraints

which connect the handle to every other part.

Make sure Part0 is the handle on every weld.

Now ensure that your tool is the correct size

relative to a Roblox character.

You can do this by inserting an NPC

via the plugins Rig Builder menu

or by inserting an NPC from the toolbox.

Drag the tool into the starter pack

and then click the play button.

Click the tool in the toolbar or press 1 to equip it.
