prusaprinters

<p>I upgraded my Ender 3 Pro to direct drive. I needed a roller so that I could put the filament spool behind the printer in a filament dryer.&nbsp;</p><p>This is a modification and merge of two projects.&nbsp;</p><p>1."Filament guide with roller - Ender 3" from <a href="https://www.printables.com/social/284238-tomaskom"><strong>Tomaskom</strong></a><strong>.</strong></p><p>2. “Ender 3 Direct Drive Filament Guide” by <a href="https://www.printables.com/social/158627-danny3945"><strong>Danny3945</strong></a>.</p><p>You will need: 2x M4x10 screws<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;2x M4 T-Nut</p><p>You will need to print the Over the Top bracket, the roller and the axis.&nbsp;</p><p>Print the axis and roller standing. The axis requires brim or it may detach during the print.&nbsp;</p><p>I printed the axis and roller in PLA and the Over the Top bracket in PETG.</p><p>&nbsp;</p><p>This is my first posted design. I look forward to feedback and hope to help someone in the process!</p><h3>&nbsp;</h3>
