We’re starting with some open source hardware projects now. The first design is a 8x10cm PCB for a symmetrical power supply. It uses 4 capacitors with a 30mm diameter like the nice old Roedensteinthat we found lately. If the UniSieb/Shunt combination looks like overkill for you and the small SimplePower is too simple, this is the right option.

The PCBs will be available in the shop later, but if you like to create your own or modify the design, just get it from the GitHub repository.
