I'm confused... I feel like this is not enough information to describe a piece. What is this bottom to top angle? It shouldn't be bottom to top, because that's not an actual line. What you'd need is bottom to roof (but not apex) angle, and then how long that is. Unfortunately, I can create an infinite number of pentagons with these numbers...
I found out that middle angle is 117° and the tip angle is 144°.

given a board is 9 by 9 and a square is 33mm x 36mm, you end up with 297mm x 324mm (+ edge) for the board.
That gives a 27 mm difference in width/height of the board whatever size you make the edge around the grid.
As all of the pictures of Shogi boards I've seen indicate that this edge is (almost) equally wide on the sides and top/bottom, the given square dimensions of 33, 33 cm on 33,66 cm seem incorrect as this is a 3 mm difference instead of the calculated 27 mm
Watching one of the Youtube video's you listed (https://www.youtube.com/watch?v=h9zb5udfeWo) it's mentioned that the dimensions are 12 sun on 11 sun. As a "sun" is an old Japanese scale unit that corresponds with 3,03 cm, you would end up with a dimension of 33,33 cm on 36,36 cm
Information about the game itself, and also the resource of a lot of used pictures
Thank you all out there who helped this gist! You are the faithful guardian of the republic 🤞🌌

Woah bro. That is next level.
Your efforts will not go without reward from the universe 🙏
I hope I helped you out a little!
If anyone makes the set by this gist please post it below here! It would be nice to see your work (I will post mine to it's just under process 😃)
As per https://www.shogi.or.jp/faq/item/
Board (33.33 cm × 36.36 cm)
Vertical = 1 尺 (shaku) & 2 寸 (sun) or 12 寸 (sun) = 36.36 cm
Horizontal = 1 尺 (shaku) & 1 寸 (sun) or 11 寸 (sun) = 33.33 cm
Margin = 2.5 分 (bu) per side (7.575 mm or 0.7575 cm)
9x9 Playing Area (31.82 cm × 34.85 cm)
Vertical = 36.36 cm (12 sun) − 1.515 cm (2.5 bu × 2) = 34.845 cm
Horizontal = 33.33 (11 sun) − 1.515 cm (2.5 bu × 2) = 31.815 cm
Each Square yet not Really Square (3.54 cm × 3.87 cm)
Vertical = 34.845 cm ÷ 9 = 3.8716666667 cm
Horizontal = 31.815 cm ÷ 9 = 3.535 cm
I've not found dimensions for the komadai, but they seem to have a flat surface about 3 spaces long, square (e.g. for your measurements, 108mm), with some further extension of the edge around that, beveled or routed. Height-wise, they seem to come either flush with the board, or no more than a couple piece-thicknesses below the surface of the board, but never above the board.
