Ratrig rollers 300 - 500

prusaprinters

<p>A set of rollers that will prevent the panels from colliding with the frame.</p><p>=&gt; Roller and axle need to be made from 2 different materials, preferrably PET for the axle/Base and</p><p>=&gt; Only 1 axle is needed. Prepare the print by printing 1 axle, starting with the largest inner diameter 85, and work through the 82, 80, 77 and 75 variant in PA until the roller is freely rolling on the axle with minimal fit. If the roller is not bulging sligtly over the rim of the holders take a smaller diameter and expand it in the slicer.</p><p>=&gt; Print the puffer in PA and press it into the lid 3030 profile for buffering.</p><p>&nbsp;</p><p>BOM:</p><p>General:</p><p>12 M3 Nut for 400 and 500; 6 M3 Nuts for 300</p><p>8 M3 rotation Nuts for 400 and 500; 4 M3 rotation Nuts for 300</p><p>4 squash head or imbus M3 * 30 screws for 400 and 500; 2 squash head or imbus M3 * 30 screws for 300;</p><p>2 Washers 3.3 * 8 or 4.3 * 15</p><p>12 Washers 3.2 * 7</p><p>4 squash head or imbus M3 * 16 screws for 400 and 500; 2 squash head or imbus M3 * 16 screws for 300;</p><p>&nbsp;</p><p>300:</p><p>2 Rolle (determine correct tolerances) printed in PA</p><p>1 roller_300_400_500_back printed in PET</p><p>1 roller_300_400_500_back, mirrored and printed in PET</p><p>Back: 2 Times:</p><p>The spacer flap needs to be aligned against the back 3030 profiles for proper positioning.
