Stretched Limo Anet A8 stock Spool Holder by anhtien

Last crawled date: 3 years, 1 month ago

The stock Anet A8 spool holder is converted into a stretch limo version, the regular M8 type of rod is replaced by the T8 type of rod (500mm in the picture). The T8 type of rod is the same as the Z-rod in the Anet A8 printer.
The base rail comes with few types: the end bracket, the 100mm middle bracket, and the 200mm middle bracket. Each side of the rail needs 2 x end brackets, one or more of the middle brackets. The end brackets were made slightly shorter in order to have room for some end nuts. For instance, the 300mm T8 rod needs 2 end brackets, one 200mm rod in the middle per side (two sides required for the set). The brackets are tied together by M3 screws and nuts (M3 8mm or M3 12mm).
Now, the base rail itself will need some support, there are two type of rail supports: one is snapped underneath (type 1), and one is screwed into the rail (type 2). If you use the rail support type 2, then you need the longer M3 screws (maybe M3 16mm). The spool holder's end brackets with the little tabs can not hold many spools of filaments at 1kg each, at least one rail support bracket is needed.
A filament guide is provided to snap onto the rail to hold the filament in place when not in use, suggest to use the type of spool holder that uses the 608ZZ ball bearings (such as https://www.thingiverse.com/thing:2476592)
The T8 rod will need spacer and end nuts (https://www.thingiverse.com/thing:2512596)
For long rods, the rod support might come in handy too (https://www.thingiverse.com/thing:2512926)
Printing:
It is strongly suggested to use as much infill as possible (70% or more) for the rail brackets, other pieces can be printed using 20% or 30% in fill.
