I got 100 x 3030 T nuts and 50 x 2020 T nuts and then 150 bolts to fit. Only 2 motor pulleys in total are needed (I'd used the 2 spare ones on my ebay printer). Each 2 m belt nicely fitted the printer, with around 300 mm spare. I had two kits each consisting of 2 motor pulleys and 2 m of timing belt. I have stock of m3 nuts and bolts and electronic components. I used two stepper motors from my ebay printer for the Z axis (I'd replaced them with higher resolution ones). Perhaps my BOM will clear up some ambiguity in the official design. When I started T nuts could only be had on Aliexpress, a couple of months later they had appeared on ebay at much lower prices.

The full "BOM" is given below, I've included prices for interest, but things change fast. Of the ebay and Aliexpress items everything except for some bolts came direct from China. I sourced all the parts from ebay and Aliexpress except for the 30 extrusions which came from a local UK supplier KJN. As is standard the X rails are 8 mm diameter, Y rails 10 mm and Z rails 12 mm. When talking about left and right I am facing the front. I call the cube face with the two XY motors on, the front. The "cube" is 500 mm high, 460 mm deep and 480 mm wide. I built the dual Z axis version, but used stepper motors with couplers and 300 mm lead screws.
For the X axis I opted for 450 mm rails and for Y and Z 400 mm.
I didn't want to cut linear rails and so used the available sizes to set the dimensions of the printer. The Core XY design of the HEVO meets both these requirements.ĭeciding the size, I didn't really want anything bigger than the standard 210 mm square, but there was the temptation to future proof by making it bigger. The Hypercube Evolution (HEVO) appealed because I had come to the conclusion a 3D printer had to be rigid and accelerate as little mass as possible. Build log for my Hypercube Evolution printer - which took from June until October 2017Īfter improving my cheap ebay 3D printer until it was so ramshackle I had no confidence it would work for long, I decided to build something better.
