Urza’s Toolbox has switched from printing in PLA to use ABS. Until recently, all Urza’s Toolbox shufflers were printed in PLA. We appreciate the color options, durability, and superior recyclability of PLA. Unfortunately, the heat tolerance was becoming a problem. Several shufflers were deformed and partially melted when shipping in the summer, or to warmer climates.
We tested heat-resistant PLA blends, PETG, and ABS, and ultimately decided to switch to ABS, as it provided the superior heat resistance, and structural strength needed to meet our requirements. ABS is the same plastic used in cars and many other plastic materials that need to be strong and heat resistant. Sadly, ABS is more limited in color options, so some colors can no longer be offered. But not melting in your car on a summer day is a good trade-off!
We will be selling the remainder of our PLA models at a discount, so watch for those models to be offered soon. All “2025 Edition” shufflers will be printed in ABS.
