Description
This is an Internal spool holder for the Elegoo Centauri Carbon wihch brings down the with to around 410mm. I placed the spool inside so that 2 units can fit my shelf.
additional parts needed: -Screw M6 (12mm-16mm work. Longer is recommended) -Centauri Carbon 7.5 mm Panel Spacer by Synthetic Electron 3D (https://www.printables.com/model/1320975-centauri-carbon-75-mm-panel-spacer)
Assambly: -Pull out the ptfe tube completely. -Unscrew the left panel and the back panel. -Remove both parts of the original spool holder. The part one the inside is held in by 4 hex screws m3. -Remove the filament sensor and place it in the same position on the inside. -Put the ptfe tube back in following the path of the print head cable while keeping the radius of bents as large as possible. Use a small screwdriver or something like that for help but be careful to not damage any cables. Don't cut the tube or the radius of a bend could be to small and filament gets stuck! -Install the side panel with the 7,5mm panel spacer by Synthetic Electron 3D . I recommend laying the unit on its left side because this can be a bit tricky. -Plug in the cable and ptfe tube in the filament sensor. -Pull all excess ptfe tube to the print head to increase the radius of the bend in the ptfe tube there. -Check if filament can pass through to the print head with not to much friction and adjust the tube accordingly. -Put the back panel back on. -Place the internal spool holder on the inside by pushing it on the standoffs. The standoffs are not squared. if it wont fit try rotating the spool holder by 90°. -Place the screw plate on the outside and secure everything with the M6 screw. -Put on your favorite spool of filament and secure it by simply twisting the spool plate on.
