linear bearings holder for aluminium Y-carriage

thingiverse

This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/6n8BAnUlg3l I'm building a new platform for the heatbed using 2 aluminium plates with 3mm of thickness. The original MDF platform (Y carriage) is too unstable and warped with the time, making it impossible to get the heatbed to be perfectly levelled. This holder is meant to be ziptied to the platform and glued in place too. I'm also intending to build a new heatbed with the second aluminium plate and nickel-chrome wire, insulated and glued in place with kapton tape. As soon the wire is delivered, I'll measure the resistance and calculate the right length for it to work. The original heatbed may have other uses (to keep the coffe hot??), it worked for a good time, but warped with the heat (I guess) and the tension applied on it.
