@kirk In general this is exactly the way how all of us should act here (and in all other open source projects). But it is always better to have something like this in advance and it does not harm. I highly welcome to have a written code of conduct. Thanks Kirk, for taking care.

Hey Everyone. I designed and printed some PLA sleeves to go over M6 screws so that you don't need to use tape on the screws anymore with the kit. The tape is often hard to properly wrap around and imo has to be changed quite often, so this should improve the design. I printed these on a Prusa Core One using a 0.4mm diameter nozzle. The screws don't come into contact with active material, so you can use PLA for this (doesn't have to be PP, although this should also work).

Let me know what your experience is with other printers!

Second cycle already showed heavy degradation, so I stopped the test [image: 1756793699759-996048f2-9ba6-4c8f-bcae-7d5e4888392d-image.png] Will wait for the Mg, Ca chlorides before doing another test. Just urea doesn't seem to work well enough.

I'm no expert ether. We used quick setting plaster a lot in construction for repairs on a lot of things and now they have a "wood epoxy" which is an epoxy for wood repairs. You have a thing epoxy you brush on onto wood which provides a good bonding surface for dry rotted wood and then you mix an epoxy that works more like the quick setting plaster and creates a strong enough repair that you can nail it. These plasters and epoxies could be formed or poured to create a nice mold. For the quickset we could build up an area, then carve and shape it before it fully set. The surface is very smooth and with a spray sealer of some kind should be even better for molds. A quick look into casting, it looks like the most common is using silicon for making the mold. Yes it lets you do detail, but it is also soft and flexible. Not good for making thin plates without warpage.
