Prusa i3 MK2 (MK3?) Spool Holder / Spulenhalter

thingiverse

translated with Google translator: Hello, The original spool holder from Prusa Research for the MK2 did not convince me. This is my variant of a spool holder for this printer. I certainly tend to construct things like that a bit over-stably, but that does not have to be a mistake. (At this spool holder the printer could be worn too ...) Besides the printed parts you still need: 2 pieces M3 square nuts 2 pieces M3 x 30mm cylinder head bolts 1 piece 8mm threaded rod (about 200mm) 2 pieces M8 nuts 1 piece M8 washer (24mm, optional) The assembly is more than easy ... The spools themselves are best placed on corresponding adapters on the axle. like this: https://www.thingiverse.com/thing:734279 or this: https://www.thingiverse.com/thing:601401 The .stl files are optimized for printing with 0.2mm layer height, 0.3 should also fit. The screw holes in "part_b" are intentionally not continuous, this is to facilitate the print. The thin membrane (0.2mm) can be easily pierced after printing. The clip effectively prevents unwanted movement of the spool on the axle.
