bathtub size U-Tube, it is a large print item, I recommend a full roll of filament, I printed it with ABS- I had some issues with printing the fit couple of pieces,warping, but it was my printer bed, the files were fixed with sli3er and printed with pronterface. this is a multi-hour print, you need at least a 130 mm high printer.I made one the credit goes to chris and Skimbal ,I had to fix some of the sides and just keep my files the same to save space on my laptop, this is final, one coat of clear coat, and I hope to take it to maker fair Raleigh.
