Counting matching models…
Two 5x10x60mm magnets fit nicely in the slot and covers 12 tubes. Seems like this size magnet is easier to find on amazon, can confirm that the DIYMAG N52 bar magnets work to hold beads from various kits.
Desiccant bead hold that fits inside most filament spools.
They no longer make replacement parts for this electrode so I designed a replacement. Used an old platinum wire from a different part we had. If you want to do it cheaper make sure you use some sort of anti-corrosive wire like NiTi or AgCl.
Printed with blend of abs-like resin/nylon resin - should also work well with a semi-flexible filament like PETG, PLA might be too brittle.
You will need to hammer the cap on, there is a retaining lip that you need to press past. Print in something strong like ASA.
These are all currently available results.
