Yet another resistance decade box

I have now ordered more resistors, and they should arrive by the end of next week.

Ordered 2x kits!

I'm going to order the larger switches and design an MBB pcb for them, too. Since it will be larger, maybe a version for through hole resistors (higher wattage?) would be a good idea?
Anyway, glad to see my simple hack is getting popular! :)
Make sure you post some pics of your finished decade boxes.

So here's a question
what is the preference for the jacks?
do most envision plugging bannana plugs in or test probes or bare wire?

I would probably go for terminal posts on the back so I have a choice of bare wires or banana plugs.
For use when prototyping on breadboard it would be nice if the top and bottom had guides to hold a piece of strip board where a couple of bits of 2.54mm socket strip could be soldered. There could be a small rectangle hole in the front next to the switches where this could stick out to be flush with the front.
When you are prototyping on breadboard you could then just plug your normal jumper wires directly into the socket and the whole unit would be as close as you wanted to the prototype and visible. For other uses you still have the option to use the terminal posts at the back.

There is a company very local to me who does 3D printing so if you have a finished design but can't print it yet I would be happy to get a test done and post photos etc... Here are the details of the printer they have :-

They charge £0.30 per gram which I have no idea what the normal rate is. Any idea how much the case would weigh? I am guessing very little.

Binding posts are pretty flexible when it comes to connection variety. That's what are on my IET decade boxes.
The RBox Mini only uses two posts and places them on the side of the enclosure, if I recall correctly.

Yeah, folks can choose which panel they want to print.
--- Quote ---for me personally I'm probably going with these so my initial design will be based on them

Would jacks require more internal space (i.e., larger enclosure)?
