The Geeetech I3 Pro W is one of the cheapest 3D printers on the market (2018). It suffers from some design issues. One of them is not enough rigid frame. To make the entire construction of the frame stiffer, I decided to make an 15mm thick acrylic frame. To do that I also had to create the 3D model of the printer first. If anybody needs the 3D model of the printer, the STP for downloading is here. Please note I tried to make everything as precise as possible, but I do not take any responsibility for any problems.
