QUBD Two Up MDF base Rebuilt / Redesign
Description
The MDF frame of my QUBD Two Up was coming apart and I had all kinds of band aids on it to stabilize it. I decided to re-design the frame to have a definitive solution and not worry about the frame coming apart. I have designed a few parts that need to be screwed into plywood or a wood table/desk. Please see pictures for reference. Disclaimer: I am a hobbyist and not a designer. I designed the parts with Sketchup on my spare time. They work for me and tolerances might not be up to professional standard. Please feel free to remix if you feel the need. Other 3D printed material required to make this work: - Bearing Cages for linear bearings: https://www.thingiverse.com/thing:1305794 You Need to print 2 for each bearing. - Twoup Y-table frame replacement by Tony_921: https://www.thingiverse.com/thing:1038960 with my remixes to accomodate for a lower position of the Y belt/motor: https://www.thingiverse.com/thing:3122476 and use 6-32 nuts and bolts : https://www.thingiverse.com/thing:1841487 Hardware: I am located in Canada and it's difficult to find metric hardware. So everything has been designed for imperial hardware. I used 6-32 nuts and screws. I purchased different lengths: 2 in, 1 in , 3/4 in and 1/2 in. I also used 6 x1/2 wood screws to secure the parts to a plywood. See pictures. You'll need plywood or some other surface to affix the parts to. Parts to be printed: My printer has a second Z-Axis motor to add stability to the X- gantry. If your printer does not have the second Z-Axis motor you can avoid printing " Z_Axis_Motor_Base_B_Final.stl " . You can then print 1 of each file except " Base_Linear_Bearing_LONG_Final.stl / Base_Linear_Bearing_SHORT_Final.stl " . You can print two of either one or one of each. What you see in the picture is the longer one but you can use the shorter one to use in conjunction with this https://www.thingiverse.com/thing:329623 to reduce play on the table frame without loosing printing space.
