I made a merge of these two:

• Teacher's Table and Chair

• Student's Table and Chair

to avoid lagging when too many entities are placed in the same place.

• you can sit on all the chairs even with the ones merged with a table

Here is a video that shows you all the equipment (from the first release):

I only have a vague idea for this before so thanks to a subscriber on my YT Channel for suggesting a detailed description of what items to put.

Also, I am making a map of a school with this addon though it only constitutes a room as of now. Take a look:

If you have any suggestions of facilities to add, do comment down below as well.

Update

Version 1.0.7 - Click here to watch the youtube shorts School Equipment update!

The added animated printer:

• Lights up when switched on
• Right click or press "Open Printer" to start the printer and begin printing
• You can force shutdown the printer even while it's still printing by crouching and it will close right away

The animated locker:

• Right click or press "Open Locker" to open a single locker compartment
• Crouch then right click or press "Open All Lockers" to open all the locker compartment

• See the video on the text link for more reference on these two!

Version 1.0.9

• "The Cube" 
  - the cube is the equivalent of a globe model of the Earth in the real world. But you are in Minecraft so the world is square! (see changelog for more details)

As usual, I am open to suggestions and sorry for not being able to reply to the comments but I do read them so feel free to write down below what more features or items you would like to be added.
