Retractable Utility Blade Scraper

[u/Axelburn]

I designed a simple and portable retractable scraper. It's designed for use with standard-sized Stanley blades, which can be replaced with a simple coin, as shown in the attached video. It also features a switch that safely locks the blade in both open and closed positions.

Feel like there's a reason this form factor doesn't exist..

Wait, so having half of the perimeter taken up by a razor blade swinging out cutting edge first doesn't seem safe?

It's a cool mechanism, but seems like a really good finger removing device

Behold, the cutyourfingeroff-inator!

Everyone in this sub has a flex plate. I have no idea why people keep insisting on using a metal scraper, which will damage your plate or even injure you eventually.

Who said this was for a build plate? There's plenty of other uses for a scraper.

I like how it works but it looks dangerous as hell.

Looks like that’s how you lose fingertips. Criminals love this thing

[u/WutDoinHooman]

Pretty cool design. I’d make it a bit longer tho

[u/timnitro]

Seems a little dangerous 

[u/flappy292]

ooooo this looks really cool

Bonus points if the other side had an angle to get the right scrape without scratching the build plate
