Bench Power Supply Adapters for common connectors
Banana to Barrel Jack Adapter is an open-source printed circuit board by baldengineer, from the baldengineer/Banana-Plug-Adapters repository on GitHub, published under the MIT licence. It is a 2-layer board of 34.3 × 26.6 mm with 32 parts on 4 nets, routed with 4 tracks and 12 vias.
It is built around the SMBJ6.0A. Its parts include 3 diodes, 3 connectors and 2 resistors. It belongs with the interfaces and adapters boards of this library.
Banana Plus to Barrel Jack Adapter
This design is intended for center positive.
The intended barrel jack is the GCT_DCJ200-10-A. However, several others will fit.

It measures 34.3 × 26.6 mm and has 2 copper layers, 1.6 mm thick.
32 parts, built around the SMBJ6.0A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the baldengineer/Banana-Plug-Adapters repository on GitHub, at the commit this page was made from: the board is banana to barrel jack/Banana to Barrel Jack Adapter.kicad_pcb and its schematic banana to barrel jack/Banana to Barrel Jack Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
