<h3>X-Maxx Basher Block</h3> <h3>Center drive shaft support block for 6s/8s Traxxas X-Maxx</h3> <p>Four versions... One that uses bearings and one that does not, with and without fluting for extra space to use grease.</p> <p>Bearings used are (Qty 2) R1212-ZZ - 1/2 x 3/4 x 5/32</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Ender 3</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Doesn't Matter</p></div> <p><strong>Resolution:</strong></p> <p>Whatever</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>at least 20% (3 or 4 walls)</p></div> <p><strong>Filament:</strong> Whatever Doesn't matter <br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>2/20/21 increased tolerances for shrinkage of some filaments, added versions with no logos, increased wall thickness around versions with bearing.</p> Recommended to print vertically standing on end. Block with bearing should use support (normal, touching build plate, support overhang "80", zigzag) <p>I've made mine using PLA. In use I've found that it works very well and will take some serious abuse. The block without the bearings actually won't break if made from PLA (least I couldn't break it). But the block with the bearings... eventually the walls around the bearing will break. I actually don't know of any material that wouldn't eventually break just because the walls are pretty thin but I ended up bending the shaft before this actually happened. The shaft didn't bend in the middle supported by the brace but toward the front bulkhead and the wobbling of the shaft is probably what ended up breaking it.</p> <p>The center drive shaft is 1/2 inch or 12.77mm. The R1212-ZZ 1/2" x 3/4" x 5/32" was the only bearing I could find that worked in this design and are easy to find. This leaves the printed walls surrounding the bearing pretty thin. If the bearing doesn't fit don't force it. Dremel some material away, use a heat gun or something, possibly place in oven to soften the plastic so the bearings will go in without force.</p> <h3>Attention</h3> <p><strong>CC license</strong></p> <p>Part of why I work on and post these files is because I wanted said part or mod and can model it myself, no commercial or better parts exist, and I simply enjoy creating. I personally hate people selling FDM printed stuff online though. FDM 3d printing is awesome but, in my opinion just not awesome enough to sell those parts to someone. I also understand there is a need/want for them as well since not everyone has a 3d printer. With that said part of the CC license I chose to publish under is "Non-Commercial and Attribution". This means no profiting off my work, selling the .stl's or printing them and selling the final product, also giving credit for using one's work. I spent time on designing these things and posted it for everyone to freely use as (<em>PERSONAL USE</em>) and (<em>NOT FOR COMMERCIAL USE</em>). Even though I hate it... I'll ignore the violation of the CC license so long as you add in the description that this is not my (your) design, give credit to me (Erin Newman) or (GonzoStrange) and add a link to this page. I think this is fair since if I did want to sell the parts as well, I would have to compete with you to sell my own work.<em>Even without asking (as its part of most of the cc licenses) attribution should always be given to the author when using their work.</em></p> </div></p></p> Category: R/C Vehicles
