Based on Holspeed's excellent Ender 3 Filament Roller Guide. It's the same as the original other than some very minor modifications. You don't need this remix if you just want to print one and use it as is. I'm putting this here because I made a STEP format solid body model for use in one of my projects. I thought someone might find the STEP version useful.
