This set of attachable and adjustable canvas levelers were carefully crafted by an Acrylic Pouring Artist for Acrylic Pouring Artists from the ground up and is copyright protected. I ensured that it is durable, sturdy and functional, designed around my 6+ years of experience as an Acrylic Pouring Artist. This Acrylic Pouring Tool was created for use in Acrylic pouring to help keep your canvas level. They are super easy to use. Just put your canvas on top of them (optionally attach small or large push pins) and dial them up or down until your canvas is level. This is one set of four that will allow you to independently adjust each corner for a perfect level every time. Level not included. Dimensions: Closed 2 1/2 inches tall Open 3 3/4 inches tall Why did we choose PLA Filament to 3D print? We chose PLA primarily because its biodegradable. When its practical, we should all do a little to reduce our carbon footprint :) Also, because its strong and resists warping. ABOUT PLA: It’s a hard material, but PLA is not a perfect material and, just like every other plastic, has some disadvantages. The low melting temperature also means low-temperature resistance. Parts start to lose mechanical strength at temperatures over 60 °C. Never put these in the dishwasher or soak them in scalding hot water. Clean soon after using. © COPYRIGHT PROTECTED!
