V-Core 3 front belt tensioners

prusaprinters

<p>A small remix of the front belt tensioners originally prepared by Liam Venter (<a href="https://www.thingiverse.com/thing:5176411">see link</a>).<strong>Remix contains just top plates (red part in the attached pictures)</strong>, for rest of the parts please visit source design.</p><p>Note: RHS_packer is a part of the Top_left_plate.</p><p>Be aware that you have to already use Liam's "Ventermech" solution, ie. front Z linear rails are not located on original place. Top front 3030 profile has to be shifted 60-70 mm below. Proper distance depends if you already use "front leadscrew guides" (then you have shift profile up to 70mm below). I shifted 60mm with modified leadscrew guides (see last two pictures).</p><p><strong>Hardware</strong></p><p>1x 5x36 mm pins (right front idler)</p><p>1x 5x33 mm pin (left front idler)</p><p>I tried to use bearing pins but theirs OD was too big and I couldn't put it through bearings (MR125/MF125) so I cut off thread and head from M5x60 and used smooth part as a pin.</p><p>2x M6x35 cap screws for belt tensioners</p><p>2x standard M6 zinc nut for belt tensioners</p><p>4x M6x55 cap screws for clamping front idler stationary blocks</p><p>4x washer (shim) for M6 screw</p><p>4x M6 nylock nuts</p><p>10x M6 T-nuts</p><p>4x M6x12 cap screw</p><p>2x M6x14 cap screw</p><p>4x M6x16 cap screw</p><h3>Print Settings</h3><p><strong>Printer:</strong></p><p>V-core 3</p><p><strong>Rafts:&nbsp;</strong></p><p>No</p><p><strong>Supports:</strong></p><p>No</p><p><strong>Resolution:&nbsp;</strong></p><p>0,2</p><p><strong>Infill:</strong></p><p>20% gyroid</p><p><strong>Filament:</strong></p><p>up to you up to you</p><p>up to you</p><p><br>&nbsp;</p><p><strong>Notes:</strong></p><p>I used PC Blend+15% CF with 5 perimeters.</p>
