DreamCast Twin-Stick Extra Button Panel

I'm a fan of the SEGA's IP back in 90's: Virtual-On Cyber Troopers. And this is an extra button panel for modernizing old Dreamcast console's twin-stick into PS4 compatible, and later on.==========[Mandarin version]https://m.gamer.com.tw/forum/C.php?bsn=154&page=&snA=100After found out there's a Virtual-On series collection released on PS4, along with many active players online, I started gathering all the gears needed to enjoy the game. Link to the collection:https://store.playstation.com/ja-jp/product/JP0177-CUSA16156_00-VIRTUALONMP00000The featured twin-stick, which made the series distinguished to other arcade machines from the start, is No.1 on my collecting list. After some history digging and surveying, I found the Dreamcast's twin-stick (model No. HKT-7500), for the legendary console by SEGA back in '90s, is the best solution for modding into a PS4 / PS5 / PC compatible one, in terms of costs and efforts needed. This twin-stick can be easily modded by exchanging the internal PCB, and has only one defect: the yellow spring sleeves is tend to break in short time, thus spare parts will be required for long term playing. HKT-7500 also has a major advantage over newer solutions, like Hori's or Tanita's: it has much smaller footprint on desktop, made it more suitable to be used in tight space.In my estimation, a complete DC twin-stick assembly, adding this extra button panel on, should costs lower than $200, if you have a qualified 3D printer. Lower than $150 if you have both a qualified printer and a DC HKT-7500. Even lower, if you don't need online audio capability, than $130.Here's the major description to the model:1. Max dimension of parts is 180x120x96mm. Suggested print setting is 3 layers of wall, 20% fill, 0.3mm layer thickness. You may set the layer thickness finer, if printing time is not an issue.2. This button panel provides max 4 more extra buttons for DC's TS, which are required to access menus in PS4. (these are PS / Option / Share / and touch panel button)3. This model is supposed to work with Brook's "PS4+ Audio Fighting Board", for its USB-B / audio jack board. You may use other boards as well, once they do fit inside the twin-stick's housing.https://www.brookaccessory.com/detail/09922855/There's a cheaper model without audio function, costs $20~30 lower, but you have to do all the soldering, or contact crimping/connector making, by yourself however. I am using this board too.https://www.brookaccessory.com/detail/58690501/4. Though I tried to make this panel a perfect fit, this version of model has only passed 2 iterations, and was not throughly verified with an actual print. It is noticed that you may have to do some minor sanding on printed parts. Any suggestions of tweaking this model are welcomed.
