Ender 3 Sprite MGN12H Linear Rail Conversion
Description
With this model I converted my original Ender 3 clone (but heavily upgraded) to use a Creality Sprite all metal hotend and a linear rail for the x axis. You don't need to worry about supports for the screw head insets around the MGN12H mounting holes. The first layer or two may be a little messy, but there are a lot of layers after that, so you can just trim the mess instead (if you have any, like I did). One of the original screws from the top wheels can be reused to attach the rail mount to the Sprite carriage, though this screw may rub on your rail. I just cut my screw shorter to avoid this. Before switching to the Sprite the printer was temperamental but now I get great prints every time, as long as I have good bed adhesion for the first layer.
