80x10mm Coupon Holder for Wear Testing

thingiverse

This device is specifically designed to hold an 80x10mm coupon of oak, which serves as a glide on aluminum extrusion for wear testing purposes. The oak block was consistently lubricated with Valvoline Synpower full synthetic grease every 200,000 repetitions and successfully endured 1.5 million cycles of movement, consisting of 100mm forward and 100mm backward motion. This is equivalent to printing 72 rolls of filament. A total of 4 pounds of weight was applied during testing. Additionally, the aluminum extrusion arm features hinge plates that facilitate the movement of the oak block.
