![Tiny 2x3 Dropdown Staircase [Tutorial]](https://i.ytimg.com/vi/Kzhx-tkrz5c/mqdefault.jpg "Tiny 2x3 Dropdown Staircase [Tutorial]
This is a tiny 2x3 dropdown staircase which is built by me.
The front triple piston extender is built along with Kwipla a while ago. I implemented the concept and parts of the circuit into this door.
At the start of the video, the door is named Dropdown Ceiling Staircase. The word Ceiling should be omitted.
As different redstoners have different opinions on the calculation of the door size, I have included both possible sizes according to different regulations. It is officially 120 blocks, but 96 blocks without calculating the ceiling block.
The tutorial format is quite different from other doors as this is an unusual door and the door blocks (staircases) are dropped down from the ceiling. Sorry for anyone who has difficulties when following the tutorial.
This door is suggested by a former discord member in Kwiplas discord and is built on request.
Feel free to comment down below if you have any problems when building this door or want a further explanation for this door.

![Smallest 7x7 Seamless Cave Door [Explanation]](https://i.ytimg.com/vi/M7EDVlwfiL8/mqdefault.jpg "Smallest 7x7 Seamless Cave Door [Explanation]
This is a 2-video series on the tiny 7x7 Seamless Cave Door I built. It has a super high density, at 92.08%, and is only 13x13x6=1014 Blocks, currently the smallest in the world. This door also holds 3 records simultaneously.
This door previously ties with the smallest 7x7 Cave Door and serves as a contained fix for the previous record, thus originally having 6 records, as described in the video. However, as there are new smallest 7x7 Cave Doors built after the recording, this door no longer holds the 3 respective records.

![4x4 Shutter Door [Tutorial | Explanation]](https://i.ytimg.com/vi/QIGo-F0-0w0/mqdefault.jpg "4x4 Shutter Door [Tutorial | Explanation]
This is a tiny 4x4 shutter door by me and lum3nd0. It has a nice and sync animation and at only 360 blocks.
Feel free to comment down below if you have any problems when building this door.
Explanation point(s) that I forgot:
- The bottom middle double (yellow) does the retraction by the powering of the hopper from the redstone block followed by the observer. The piston adds 1 tick of delay, resulting of an accumulated delay of 3 ticks to the hopper, and the floor block is powered at t=4 which buds the piston and will retract at t=5.
There is an unlisted video with more detailed (and rambling) explanation video, you can check it out here:
