Better Traxxas 2WD Magnum 272 Transmission (Requires RPM Gearbox Parts)

prusaprinters

<p><i>PLEASE NOTE: YOU MUST HAVE THE RPM GEARBOX IN ORDER FOR THIS TO WORK, THE METAL MOUNT AND A-ARM ATTACHMENTS ARE NEEDED FROM IT</i></p><p>I needed a much bigger motor mount for my Rustler 2WD, so I remodeled a RPM gearbox without the cover mount/wheelie bar mount to accommodate huge motors.</p><p>It's snug, but I can fit a Castle 1717 1650kv motor in there with 18/47 mod 1 gearing (planning on installing taller gearing soon), I'm also planning to run it on 8S which is completely overkill, but I really want to make a custom 3D printed chassis too.</p><p>This isn't anywhere close to being final. I want to find a way to add the wheelie bar back without interfering with the huge motor. I posted this now because the gears, bearings, and extra bits fit and spin perfectly. I'm posting Solidworks files so anyone can edit/add their own thing.</p><p>Supports are needed everywhere except the holes, and print upright. The L transmission case cannot print face down, so it needs to be printed standing up, with lots of support. I should've made this more 3D-printable, but that's to come in future versions which I am planning to do, since I want to make an 8S rustler.</p><p>Notes:<br/>Any driveshaft cup diameter 11.5mm or lower will fit (MIP driveshafts work perfectly, I have them installed)<br/>This upgrade is intended for cars with the original Magnum 272 transmission (non-R) with the RPM gearbox upgrade.</p><h3>Print Settings</h3><p><strong>Printer Brand:</strong></p><p>Prusa</p><p> </p><p><strong>Printer: </strong></p><p>i3 MK3</p><p><strong>Rafts:</strong></p><p> </p><p>No</p><p> </p><p><strong>Supports: </strong></p><p>Yes</p><p><strong>Resolution:</strong></p><p> </p><p>0.2</p><p> </p><p><strong>Infill: </strong></p><p>25%, Rectilinear</p><p><br/><strong>Filament:</strong><br/><br/>any PETG, PC, anything temperature resistant &gt;100C </p><p> </p><p> </p><p> </p><p> </p><p>Category: R/C Vehicles</p>
