Having tried other tools (more than once) that turned out to have inherent layer adhesion design flaws, this tool is a brilliant solution - strong and dependable. I drilled out the hole to 4mm and used a steel M4 machine screw, washer and nut and it’s utterly robust. The pipe grip is an inspired addition that completes the ease of use. Very impressive, thank you.

Also works for the Dremel 4250, although the On/Off switch gets slightly covered. Good, very solid print.

I saw this recommended on a couple of videos. it's really useful to stop my A1 throwing its poop around like an angry chimp, but occasionally clogs if the printer gets overly creative with how much and how coiled it's going to make its poop. I've not pushed mine fully onto the support to give it a better chance to drop the poop into my container below. Overall delighted with the efficiency, effectiveness and fit of the design, thank you.
