Really impressed with my first experience on Treatstock, good communication from supplier. End result is a great replacement insert for my scroll saw (much better than the flimsy plastic one it came with)
They seemed very rough especially the portion that could touch your glasses. I just rubbed them very gently on some fine grit to knock off the roughness
Was informed about printing choices that led to best result. Printed perfectly. Snapped into system without issue and thumb grip is exactly how it was detailed in the Thingiverse page. Easily recommended!
