thingiverse

FLSUN i3 cPlus modifications: -Shortened 20x20 mm extrusions 12cm to reduce y-axis footprint without losing printable work area. -Changed square nuts to twist-tee nuts for added rigidity -Masked the electronics acrylic with vinyl -E3D V6 all metal hot end -All metal filament drive -Custom Marlin 1.1.9 firmware for z-axis offset, auto mesh leveling and steps/mm for all axes plus extruder -Modifications printed on an Ender 3 Pro out of various colors of PETG. Infill was about 80% for the functional parts and .2 layer height. I use Hatchbox PETG. From [Flsun i3 (2017) 3 Wheel X Carriage](https://www.thingiverse.com/thing:2521909) I used the carriage and x-axis limit switch bracket. This allowed for a more stable/adjustable x-axis carriage and I slightly modified the carriage. From [2020 extrusion printer (refer prusa I3) 2017/02/22 upload .STP (easy for edit)](https://www.thingiverse.com/thing:440395) I used the belt tensioners, y-axis stepper motor mount and y-axis limit switch mount. These allowed me to: -Raise y-axis to be supported on extrusions rather than acrylic plates. -Upgraded belt tensioner From [Inverted Z Kit - FLsun i3 PLUS](https://www.thingiverse.com/thing:3670906) I used the z-axis stepper motor mounts, z-axis threaded rod mounts These allowed me to: -Invert the z-axis From [Wing Nut bed level screw knob for Anet A8 (and possibly other printers)](https://www.thingiverse.com/thing:2000216) I used the "not for a8 wingnut" to upgrade the bed adjustment screws. I had to shrink them down a bit for a good press fit. In progress: -Aluminum bed mount rather than acrylic -Spool holder -Cooling fan -Linear rod x-carriage
