Sure, it's only an electrode holder.

Also is this the same plastic as Kephra's lids (kitchen cutting boards).

Yes.

If you are content for the end result to be inferior to a lathe-turned offering, a sharp chisel and a few files will adequately turn a piece of cutting-board mounted in the chuck of a drill. A fretsaw will cut the blank out of the cutting-board before you finish it off with the other tools.

Do you know of a finish product for sale? like the one at the silvertron store.

@waboni can you share your design?

Dear Edwire, sorry for replaying this late, sure I can, please PM me in order to share it with you, responding to your referral credits question, yes I suppose that they should be there, at the time of ordering there is an option to redeem credits, also note that Xometry is offering free shipping on any order right now.

I alway prefer the 1L beaker for easy cleaning and more volume production. just for you to take in consideration.

You can buy a small, cheap cutting board (HDPE) from Walmart.  Dollar stores sell them but they're small and way too thin.  A dremel tool with a milling bit as long as you're careful, you can cut a circle out of it and then make a circular channel, maybe half the depth of the material thickness to sit over the rim of the jar you're using and just drill a couple holes to push the electrodes through. The only thing you'll have to deal with is how to secure the electrodes.  Friction works but plastic wears over time and expands and contracts with changes in temperature where its better if you figure out some way to secure them.

One way is to suspend them through the hole and then attach a small clothes peg or other clip to the electrode to stop it falling down through the hole. Or use a crocodile clip for the same purpose. Or a dab of silver solder on the electrode, applied above the lid,

Though you need the appropriate tools to do so, the best I've seen is a small piece of plastic (scrap from the cutting board) with a hole in the center slightly larger than the diameter of the wire with a threaded hole in the side you install a set screw so you can gently tighten it to "capture" the wire and prevent it from moving.  The glue or secure this to the lid somehow.  For HDPE you might want to drill a couple small holes straight down through it and partially into the lid to screw it down since there isn't much in the way of glue or adhesive that will glue HDPE to itself.

If you use a knurled knob or a set screw that sticks out, you can just clip to it with alligator clips once you adjust the depth of the silver wire or copper cathode in the water though the only issue with this is that if you need to adjust it you have to remove the alligator clip.  Better probably to make the wire a bit longer so it sticks out the top more and just alligator clip that up far enough you still have some room to adjust the wire without having to remove the clip.

As long as you use a deep enough thread set screw (fewer turns is usually a coarser thread - like 24 threads per inch as opposed to 32 (6-32).

There are lots of ways to do it. This is just another to add to the list.

It doesn't have to look pretty. It just has to work (wink).

An oversized plastic lid with a Wire terminal works great as well ..

Can PLA filament be used ?
I just purchased a 3D printer , Going to design a similar lid for my set up using tinker cad 👍🏼

This (wire terminal connector) is what I personally use. After much experimenting, this is easily the most versatile.

Thank you I agree!
I just got the 3D printer and want to tinker around with it ;)
It’s mostly to print out my own electronics project boxes .

Thanks again .
