Of course, you also need to complete the three Challenges and reach the True Jedi rank for the 100%.
The Droid Factory Frenzy Minikits require you to pay extra attention to your surroundings, and even so, you have to play the mission at least twice because some of the collectibles can be obtained only in Free Play.
So consult the guide below to learn how to get the Droid Factory Frenzy Minikits.
Minikit #1: Factory Sample
The Droid Factory Frenzy mission splits your party into two teams: on one side, you have Anakin and Padme, and on the other, C-3PO and R2-D2.
Of course, in Free Play, you can change the characters.
You have to reach the first conveyor belt as Anakin and Padme and jump on the first press machine.
As shown in the next image, you can jump from on top of the press and reach the first Lego Star Wars Skywalker Saga Droid Factory Frenzy Minikit.
Minikit #2: Conveyor Belt Backtrack
After getting the first collectible, stick with Anakin and Padme to drop down to the second conveyor belt.
Here go to the left, against the direction you are led to by the conveyor belt, and you should see the next Droid Factory Frenzy Minikit all the way in the back, above a furnace.
To continue, you have to switch to a Bounty Hunter character and shoot the golden bars above the ladder to the left.
Now climb the ladder to collect the second Minikit.
Minikit #3: Fancy Fan Fix-Up
The third collectible can be obtained after dropping onto the conveyor belt with the blue barriers.
This happens while playing as C-3PO and R2-D2.
However, you have to switch to a ranged character and shoot the target above the third Droid Factory Frenzy Minikit, which is attached to a piece of machinery that moves the collectible between conveyor belts.
If you hit the target, the machinery should drop the Minikit down to you.
Another tip I can give you is not to chase the Minikit; instead, wait for the machinery to position the collectible above your conveyor belt.
Minikit #4: Art Critic
In the same area where you collected Minikit #3, you have to reach the part of the left conveyor belt blocked between two barriers.
You can reach that part by jumping on the conveyor belt to the right, going forward, and then jumping back to the original conveyor belt.
Here you have to destroy the orange bars you can also see in the following screenshot, and like that, you get access to a new area.
You have to reach the same area if you want to progress in the mission, so you can’t miss it.
You can see a painting machine on the right side of this area.
The trick here is to destroy the painting, but you can only do this when you see a Minikit on it.
With the remaining parts, you can build the next Droid Factory Frenzy Minikit.
Minikit #5: Smuggler Juggler
You first have to take the blue barrier down for the last collectible.
Then, on the droids path of the mission, go toward the north on the conveyor belt from the east.
Run against the direction you are led to by the conveyor belt until you see some silver orange bars on your left (on the other conveyor belt).
Now switch to a Villain character and destroy the bars with a grenade.
After, switch to a character that can interact with the machine in the newly accessible area, like a Hero.
Pull the Lego Star Wars Skywalker Saga Droid Factory Frenzy Minikit from the machine and collect it.
