eSun dry-box Reverse Bowden set-up, with mounts

prusaprinters

<p>Reverse Bowden set-up for the eSun eBox (filament dry-box) with mounts to locate the dry-box above the printer.</p><p>The mount fits 2020 style extrusions, such as those used on an Ender3 and is remixed from a design by <i>3DPrintSOS</i>, which is itself a remix of an original design by <i>@Colbrook911 on Thingiverse</i>. It uses t-nuts to secure it in place. I mount the box to the right-hand-side of the printer so the reverse Bowden setup is as close to the centre of the printer as possible.</p><p>The dry-box PTFE filament guide is an original design by me created in Tinkercad.</p><p><strong>In Use</strong></p><p>I have completed a guesstimated 100 odd hours with the Reverse Bowden set-up and no issues at all.</p><p>I have probably done 500 odd hours with the dry-box and it makes an appreciable difference especially with printing PETG.</p><p><strong>Printing</strong></p><p>The PTFE filament guide benefits from support, to maintain accurate dimensions.&nbsp;</p><p>The dry-box holder prints best on it's back with support for the front mount. No support is needed for the rear mount.</p><p>I printed the parts with 5 perimeters, on top, bottom and vertical walls for strength; and at 0.20mm layer height, for aesthetics. You could easily print at a higher layer height if you want to print faster.</p>
