A wonderful upgrade for edge sanding with the ETS EC 150. EDIT #2: After my previous edit, Dan from Iluka reached out and offered to send a replacement. He will be adding more infill, which will hopefully make it more durable. Thank you! EDIT #1: These are 3D printed and while they work great, they are not designed to be durable. I removed mine and set it on top of an M337 Systainer. I bumped the Systainer and the attachment fell roughly 14" onto an OSB floor and broke. This isn't the first time a 3D printed product I've purchased has broken and I'm thinking that perhaps when it comes to certain types of tool accessories, 3D printing isn't there yet. Maybe this attachment needs to be redesigned such that it can handle a shop environment? Either way, nice product when it works, its just not very durable.
