All the boxes and bags including parts for the build are labelled.
Each bag (or box) label describes in which chapter you will need it.

Most of the labels are scaled 1:1 and can be used to identify the part :-)
For the most common screws, nuts and PTFE tubes, you can also use the enclosed letter, which contains Prusa Cheatsheet on the other side.
You can download it from our site help.prusa3d.com/cheatsheet. Print it at 100 %, don't rescale it, otherwise, it won't work.

Step 6 Spare bag

Every type of fastener is included in a separate special bag.
If you lose a screw during assembly, use one from this bag.

Step 9 Important: Electronics protection

WARNING: Make sure to protect the electronics against electrostatic discharge (ESD). Always unpack the electronics right before you need them!
Here are some tips to prevent damage to the electronics:
Keep the electronics inside the ESD bag right until you are asked to install them.
Always touch the sides of the board while manipulating with it. Avoid touching the chips, capacitors and other parts of the electronics.
Before you touch the electronics use any conductive (steel) structure nearby to neutralize any electro-static energy.
Be extra cautious in rooms with carpets, which are a source of electrostatic energy.
Clothes made of wool and certain synthetic fabrics can easily gather static electricity. It is safer to wear cotton clothing.

Step 10 Pro tip: inserting the nuts

3D printed parts are very precise, however, there still might be an occasional lack of uniformity in the printed part and same goes for the size of the nut.
Therefore it might happen, that the nut won't fit in easily or might be falling out. Let's see, how to fix it:
Nut won't fit in: use a screw with a thread along its entire length (typically: M3x10, M3x18) and screw it from the opposite side of the opening. While tightening the screw, the nut will be pulled in. Remove the screw afterwards.
Nut keeps falling out: Use a piece of tape to fix the nut temporarily in place, as soon as you insert the screw in, you can remove the tape. Using glue isn't recommended as it can partly reach into the thread and you won't be able to tighten the screw properly.
Whenever you need to fit the nut that doesn't fit properly, we recommend using  "screw pulling technique". You will be reminded with Joe's avatar ;)
Parts in the pictures are used as an example.

Always check the correct position of the M3nS nuts in the printed parts immediately after insertion. Improperly inserted nuts will not allow proper assembly of parts.
Make sure the nut is inserted all the way in. Use the following methods:
Use a 2.0mm Allen key for easier insertion into the hole.
Check the hole alignment by using a 2.0mm Allen key.
Check visually if the hole in the nut is aligned with the hole in the printed part.

Step 12 Reward yourself

Reward yourself
Reward yourself
Building the MINI+ printer is a challenge unlike any other and you should reward yourself for every milestone you reach. That is why a bag of Haribo Bears is included!
The biggest issue from the previous builds (MK3S+, SL1) which we had to address was inadequate bear consumption. Many of you didn't have enough bears for all chapters, some even ate them all before they started!
After completing each chapter or challenging section of the chapter, you will be prompted to replenish energy for the following steps.
Don't eat all the bears before you start or at once! Not following instructions will have serious consequences, we are currently assembling Prusa Haribo tactical squad for this matter.
Hide the Haribo for now! From our experience, an unattended bag with sweets tends to suddenly disappear. We are still investigating this phenomenon.
All information provided in this step is based on a long-term very serious research study ;)

Step 13 How to successfully finish the assembly

How to successfully finish the assembly
To successfully finish the assembly please complete each of the following:
Always read all the instructions at the current step first. This will help you to understand, what you need to do. Don't cut or trim unless you are told to!!!
Don't follow pictures only! It is not enough, the written instructions are as brief as they can be. Read them.
Read the comments from the other users. They are a great source of ideas. We read them too and based on your feedback improve the manual and the entire assembly.
Use a reasonable force. The printed parts are tough, but not unbreakable. If it doesn't fit, check your approach twice.
Eat the gummy bears as instructed! Disobedience won't be tolerated :D
Most important: Enjoy the build, have fun. Cooperate with your kids, friends or partners. However, we take no responsibility for possible fights ;)
