    Many moons ago, the local library was saddled with a Cube3 printer. It started well but deteriorated rather quickly, especially after the manufacturer pulled all support. I was asked to recommend a...

    That's great that you have an STL file, which cuts your workload to a quarter or less.

    In the isometric view of the part, you have what I believe to be the best orientation for printing. Be sure...

    You've taken on quite a project, especially considering how new you are to the activity.

    Two primary factors, design and position/printing.

    Regardless how you position the part on the print...

    Another place an unusual nozzle shape might work is on the 6 axis robotic arm type 3d printers. The wrist typically can rotate through 360?.

    Petercat, your observation is a good one. With a non-orthogonal move, the width of the layer would be something other than the dimension of the square's width. That's the best reason yet for a...

    I expect a large portion of the reasoning is manufacturing costs. It's far easier to generate a cylindrical hole in a mass than it is to create a precision square hole. Broaching is one method of...

    @TommyDee, I have a Cube3 and two cartridges still in OEM wrapping. Our local library has given up on theirs, although it was working great the first months of operation. So well, I bought one. Now...

    If you have to disconnect your bowden tube for service reasons, the connector can become difficult to release or in a worse-case situation, not properly grip the tubing. The tubing should hold well...

    That's a silicone cover for the heat block. It helps keep the heat in and the gobs of filament clear of the block. It still gets hot, so keep fingers clear!
  10. If you're asking how to know the overall size,...

    If you're asking how to know the overall size, there are many variables that have to be turned into values. Consider at first the offset of the nozzle center to the extreme edge of the carriage on...

    I can't recall where I saw it, but it probably was a CNC machine, not too far off from a 3D printer, especially the coreXY design. My Emblaser I laser engraver is coreXY and works well as a general...

    A one inch thick bridge structure is unlikely to have much strength. Consider even a one inch by four inch piece of lumber that is six feet long. If the ends are supported, the center will bow and...

    ABS will delaminate during the print if you do not have an enclosed print area. Even a cardboard box over the printer will reduce unwanted cooling and may solve the cracking problem. What are your...

    I had a similar problem with a simple test print using PETG. I increased the nozzle temperature by five or ten degrees C. Slowing the print speed can also help in layer bonding. There's three...

    There's no real disadvantage, as far as I can determine, to increase the z-hop to clear your streaks. Make lifts in 0.200 increments for 0.200 layer height and you should be clear.

    I was unable to locate a manual online for download for the printer you own. Many slicers have a feature known as z-hop. It lifts the nozzle a small amount as the head transitions over the model. You...

    You will most certainly need support. The corners of the rectangular segment will droop substantially during the print. The overhang at the area near the cylinder may be only a couple of millimeters,...

    I'm a fan of OpenSCAD as you likely know, but I suspect the OP might be a bit of a beginner to the 3D modeling world.

    Regarding the letter scaling: take the letter A for example. The center of the...

    What software do you prefer to use for your modeling tasks? Right off the top, Tinkercad is an easy program to use. It has all the features you require to create this model in short order.

    That was an interesting project. A large portion of your model had flipped normals. These are faces for which the parameters indicate that the inside is on the outside. I was able to fix that with...

    It's difficult to determine from the photos, but it appears that the program used to create the model is SketchUp. That program is well known for creating models which will not print.

    Your model is quite large! It's certainly a good thing that you've allowed for drain holes, to keep costs down. It might be practical to not reject other methods of printing. I have a couple parts...

    Another aspect of your service selection would not be the overall volume of 230 cubic centimeters or 300 cubic centimeters, but rather if your model will fit within the build box. There is a resin...

    Depending on the topology of the model, you appear to be on the right track by providing drain holes in the model. I'm not sure why you feel it necessary to split the model, unless you expect it...
