Geetech I3W original spool holder modification

myminifactory

I have a Geeetech printer, heavily modified over time, but I've always used the original spool holder because I primarily printed with the same color until the end of the spool. Now that I find myself frequently switching between PLA and PETG, the old setup has become somewhat inconvenient, so I came up with this modification to quickly change the spool without releasing the clamps holding the axle in place.My Geeetech printer is an I3W, plywood version.The modification is quite simple; it consists of two cores that fit into the standard holder's larger holes, secured by 4 small tapping screws and 4 right-angle plates to keep the vertical plates perfectly upright (the original holder provides good support but its long sides and bottom are not squared.I cut the axle for the spool precisely to measure, and it fits perfectly inside and out without any extra clamps.My axle is 8mm in diameter, but you can choose a different size using the customizer.\r\n----------------------------------------------------------------------------------------------------\r\nI created these eBay links where you can find components, filaments, and spare parts at competitive prices.
