K280 Spool Holder

prusaprinters

<p>A 3D printable robust and durable <strong>Spool Holder for the He3D K280 </strong><i><strong>“Mega”</strong></i><strong> Delta </strong>3D printer and other RepRap <i>Kossel </i>derivatives. It should work on many other delta printers made from aluminum extrusion, including the He3D K200.</p><p>The spool holder is mounted to the V-slot of the frame extrusion, just below the lowest travel point of the effector carriage, using M4x10 hardware.</p><p>The part can be easily 3D printed, without any support, on a modern inexpensive 3D Printer. It can be printed with a variety of materials, including PLA, PETG, ABS, ASA and many other types of printable materials.</p><p>PLA works very well for this application. It is easy to print. The object should be durable, easy to maintain, and last for a long time as long as the printer will not be used, stored or kept at in a high temperature environment, exceeding ~55 C (~ 130 F).</p><p>I designed this spool holder in 2017 and have been using it since without any issues.</p><p>I prefer spool holders with some friction and my design reflect this.</p><p>I found that a little friction prevent the spool from running away / self-unwinding due the the springing action of some filaments. It also prevents filaments snaps caused by multiple quick retractions in succession.</p><p>Please note that I am including gcode and project files for both the Prusa MK2s and the K280 Mega Delta printers.</p><p><strong>Recommended print settings with a .4 mm nozzle</strong></p><p>- Layer Height: .2 mm</p><p>- 6 perimeters or shells (2.7 ~ 3.0 mm)</p><p>- 13 bottom layers (2.6 mm)</p><p>- 13 top layers (2.6 mm)</p><p>- Infill 15%~20%, depending on infill type</p><p><strong>Additional items needed for assembly</strong></p><p>- 2 x M4-10 Hex Socket Screws</p><p>- 2 x M4 T-Nuts</p><p><br><strong>Assembly Instructions</strong></p><p>1- Clamp the spool holder to the side of the extrusion using the M4 screws and T-nuts, allowing enough clearance so that the carriage can reach its lowest travel point</p><p>2- Tighten the screws enough to secure the spools holder in place.</p><p>3- <strong>DO NOT OVERTIGHTEN!</strong></p><p>&nbsp;</p><p><strong>Thank you for viewing this object!</strong></p><p>If you like it, please click on the “like” button.
