FYI: Simple tool for lifting prints

I've spent a lot of time diagnosing and preventing PEI print surface contamination over the last year. The biggest trick is to keep the ol' greasy mitts off the surface. To aid in this, I've used a couple of printed part removal wedges that have worked well. They're good, but not being particularly sharp, have a tendency to pop skirts and prime lines off across the room. I decided to try a plastic razor scraper off Amazon and wow... This thing really simplifies removing parts, prime lines and skirts without them flying away. The blades are sharp enough to easily lift parts, but not as sharp as actual razors, so I'm less likely to bleed out during a mishap.

I thought I'd pass along the tip for those fighting the good fight against bed contamination.

I posted about something like this ages ago, yes  I couldn't agree more, just do a search for plastic razor blade and you will find something similar.

Prusa should include one of these in their kits in  my opinion.

Normal people believe that if it ain’t broke, don’t fix it. Engineers believe that if it ain’t broke, it doesn’t have enough features yet....

That looks handy.  I've been using a Cricut Scraper with success.

I think it was Chocki's post that I followed and now have a box of plastic razor blade.  Not quite the cats meow - stll doesn't get under a part unless the sheet's been flexed, but they work better than my car door panel spudgers.

It is always wise to get more than one opinion......

I use a small chef's knife. Hold it at the correct angle and it easily peels off even squished on single layers. Doesn't scratch my textured PEI plates. Not so great for phenolic plates, though.

Yours matches the Prusa colors more! Wish I'd seen that one.

If you get it from Amazon, check the other offers.

I went with the same color, two scrapers, and 100 blades - for a buck more.

I've been using an old hotel key card. Maybe if I sharpen an edge it'll stop bouncing parts around.

I have been using these for a few months and love them.  They remove the print with no damage to the bed.

I've been using a pizza cutter, plastic of course. Works like a charm.

This works well if you happen to have a 3d printer handy: https://www.thingiverse.com/thing:3652806

I bought this and 100 blades.  Thanks for sharing this.  I now have 6 handles so hopefully, I will not keep misplacing them.

This is my preferred tool for removing PETG prints from PEI. Easy to slip under corners and lift parts off the build plate.

Works well with Prusa SL1 build plate too.

Found on eBay, Amazon and shops with art painting tools.

Take a look at my MK2S/MK2.5/MK3/S printer parts on Thingiverse ;)...
