AX2 2 speed gearbox cover + servo mount

<p>I have bought AX2 2-speed gearbox for my Axial SCX10. I found out that holes of original Axial gerbox cover does not line up with mouting holes on AX2. And mount for 50g servo is to long for my Proline Chevrolet Silverado body. I think that problem will be common for Honcho, Ford F150 or similar bodies. So I designed cover that will fit and servo mount for 9g servo. Servo mount is bigger than it should be but I am using it as a platform for mounting my ESC. Cover itself also could be bit slimmed but I keep it on safe side so there should be no contact between gears and wall.</p> <p>I have printed it from clear PETG on my Anet A8 with 0,5mm jet.I am still tuning setting for PETG but after little bit it fits nicely under motor mount.</p> <p>You will need 6x screw M3x8, 3x M3 nut and 2x screw M3x25. These two replace 2x M3x20 that hold motor mount on gearbox and will be short after you put cover base under motor mount. You will probably need them cut to M3x22. But with stock clutch mount it could be OK. I am using solid mount that is closer to gearbox. So I had to cut them to correct lenght.</p> <p>Update:</p> <p>-Uploaded version 3. In this version there is bit less space for spur gear but if your spur gear is not sticking out from gearbox to much it should be OK. Reason for this modification is battery mounted in front of transmission. Second modification is more sturdy base with lip. First vesrsion was not sturdy enough and bend a little. That caused gap between booth parts. So new version got thicker edge and booth parts are now overlapping.</p> <p>Update2:</p> <p>-Fixed wrong filename AX2-V3-8MM to AX2-V3-10MM. This is version for standart driveshafts.</p> <p>-Uploaded version 3 for driveshafts with diameter 12mm. My new MS Technology (<a href="http://www.mstechnology.cz">http://www.mstechnology.cz</a>) does not fit in space given by standart 10mm driveshafts. Actualy distance between stock spur and closest poit on driveshaft is only 1,3mm! Only option is to make wall thin as possible or put hole in there. I were able to position 0,5mm wall in space where it seems that spur or driveshaft does not come in contact with spur or driveshaft. This variant I consider experimental. Seems to be working but your experience could be different.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Anet A8</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>40</p></div> <h3>How I Designed This</h3> <p>Designed in Catia V5.
