Printrbot 1405 XL Tower. Printable STL Version

youmagine

I've completed the Printrbot XL Tower upgrade with a simple conversion from the original laser-cut DXF to printable STL files. The tower-top spool holder was missing in the earlier version I bought on release day, so I converted the entire pattern to include all parts and allow customization. Printrbot released the lasercut DXF drawing file, but we need converted STL to print any of those parts. Unfortunately, the originals aren't water-tight drawings into printable STL, so they have to be drawn from scratch. You can find the original DXF at https://www.youmagine.com/designs/printrbot-simple-xl-upgrade-with-spool-rack. The designs are specifically for printing, with tabs drawn slightly smaller than the holes they fit into for a tight fit and first-layer squish that may need to be filed off. Screw and nut parts are designed for original 3mm hardware use. I've had no issues fitting parts printed at 2 perimeters, 0.4mm nozzle, and .25 mm layer height (30% infill). However, using 3 perimeters or heavy layers may require editing the files or drilling and sanding to fit the parts. The thickness of the pieces is rendered at 5.6 mm thick, which fits nicely with Printrbot's original 6mm wood. A tip: for larger pieces, use less infill to reduce required filament; you can even edit the parts to be 5mm thick. The largest piece (Left Wall) requires a print area of 338mm x 142mm. The file "10x15.STL" contains 10 pieces of the "15.STL" needed to build this kit. If you use it, you won't need the "15.STL" file; instead, print one of each remaining STL files.

This is still a work in progress (I'm a beginner with CAD and computer drawing), so please let me know about any errors so I can correct them. A lot of work has gone into these files, so please share, edit, alter, and enjoy – but also give credit for others' work as well.
