nozzle wipe

@arhi I can't be sure but the stuff I used was more like this https://www.ebay.co.uk/itm/SOLID-SILICONE-RUBBER-STRIPS-3MMTHK-X-5MTRS-LONG-WHITE-60-SHORE-FDA-GRADE/331230136018?hash=item4d1edac6d2mM0icdmB-aIKG93gQRG6wvw. The listing is for 3mm thick (which is what I think I used), but the picture looks like 1mm thick. But it's definitely "solid".

This is what I have. The picture is a bit out of focus but it's solid and about 3mm x 10mm.

@deckingman thanks, I was afraid of that "sponge" part too .. both looks spongy and title say sponge .. from what I see it is insulation strip so it's expected to be pressed between something I think...

deckingman

@arhi It might still work. Or to put it another way, I do know the solid stuff works, the spongy stuff might work but I don't know for sure if it will.

Here's what I've been using with success. Tested the silicone blade and 250c nozzle temps didn't affect it. Also tried a soldering iron at 350c and it couldn't touch it. Should be safe with the temperatures I plan to use for ABS, PC and Nylon.

The blade itself is about 2.2mm wide, has a flat edge on one side and a round key on the other. Total height is about 20mm and it's 200mm long. Enough to do several printers.

The blade is easily mounted and prevented from sliding out by a wall on the opposite side. Macro starts on the side closest to the camera and zig-zags away.

I tried one blade and it didn't hold up on 200C
I ordered some of that spongy things + I found solid one too so ordered that too we'll see when/if arrives... found something super cool now amongst baby things need to test for temp might be a win ... another kitchen utencil, found between baby things ... temp. resistent

This one should sustain high temperature. It is used to hold hot solder iron tips.

The one I have is 2.3mm in thickness and the square portion is 75mm x 75. It's a rubbery thing.

@zapta ha, I have exactly the same thing that I got with my PACE ages ago, you are supposed to use it to grab your hot tip to replace with another one but it's very soft, it's like the stuff I already have in the wiper right now. This "cup" will work great till I get the long strips, it is much stiffer, and when long strips arrive cup will be cool to hold the bits of plastic

One thing I did was collect all the old and torn silicone socks I had lying around and made a wipe.

I just sliced off the sides and kept the face, then alternated them with washers. Used RTV on the bottom to bind them.

Stumbled upon this one while searching for a silicon work mat.

E.g. the 50x50x20mm.

The last 3D Printing Today (episode #349) discussed some magic 'inexpensive silicon foam' that works great to wipe the nozzle.

It starts at the 17 minutes mark. (Clicon on the POD icon to start playing, or find them on your favorite podcast player).
