<h3>Magnetic Gunstock for Oculus Quest 2 (Improved &amp; Simplified)</h3><p>After printing three of these for friends I decided to improve a few issues I found and greatly simplify the process for others. Most of the source models have disparate and confusing instructions, so I tried to put everything here in once place. The addition of the adjustable buttstock makes this feel really high quality. Generally I tried to make this a cleaner build.</p><h4>Required Materials</h4><ul><li>Normal stuff<ul><li>(2) M3x5mm caphead for cushion</li><li>(1) M3x8mm caphead for sight</li><li>(1) M3x40mm caphead for adjustable stock</li><li>(2) M3 nuts</li><li>(1) 0.5x6x20mm spring for adjustable stock</li><li>(2) #6x(5/8)" or #6x0.5" countersunk woodscrews for controllers</li><li>Loctite / Superglue</li></ul></li><li>Amazon Stuff<ul><li>(3) <a href="https://www.amazon.com/Home-TZH-Threaded-Furniture-Decoration/dp/B083XFNNYS/">0.5x8" Lightweight Steel Pipes</a> (nothing at Home Depot will work)</li><li>(1) <a href="https://www.amazon.com/dp/B085RD28JW/">32x8mm 90lb magnet for Right Hand</a></li><li>(1) <a href="https://www.amazon.com/dp/B07YBBCJ5W/">32x6mm 65lb magnet for Left Hand</a></li><li>(2) <a href=" https://www.amazon.com/gp/product/B07JGGHGF7/">optional sling mount</a> (these look &amp; work great even if you don't get the sling)</li><li>(1) <a href=" https://www.amazon.com/gp/product/B0799DDT6C/">optional sling</a></li><li>(2) <a href="https://www.amazon.com/gp/product/B07K22VWS6/">optional double-sided removable stickers</a></li></ul></li></ul><p>If you buy everything you will have enough materials to make three of these gunstocks. The parts you need end up being about 80 USD.</p><h4>Printing</h4><p>In the <code>3mf</code> I grouped all the files into “A_”, “B_”, etc so you can print each group overnight instead of one big mega print. None of the files require any supports.</p><ul><li>Groups A, B, and C should be printed in your primary color - in the photos I chose white.</li><li>Group C should be printed with a big brim since there is a large overhang to support.</li><li>Group D should be printed in your accent color.</li><li>Group E is just the buttstock cushion and ideally should be TPU but it probably doesn't matter. For this I did Archimedean Chords at low infill, with 1 perimeter, and 2 top &amp; bottom layers. If you don't print this with air it will be rock hard.</li></ul><p>Since PLA is garbage I did everything out of PETG / HTPLA+ / ASA since you get a bit of flex and higher strength overall. You should use 3+ perimeters and 15%+ gyroid infill. For rectilinear go much higher infill.</p><p>I printed some parts w/0.6mm nozzle but I think it's worth using the 0.4mm for better resolution. Variable layer height for all parts.</p><h4>Assembly</h4><ul><li>Adjustable Buttstock<ol><li>See image</li><li>Hold “B_Lock-Pin” with pliers and screw in the long M3 screw all the &nbsp;way down. This can't be easily done by hand - drill recommended.</li><li>Insert this part with the spring into “A_buttstock-body” and hold the screw tight w/pliers.</li><li>Place “D_FGC9-PART” on and thread on “A_Washer”. Leave just enough thread for both nuts.</li><li>Loctite and screw on both nuts.</li><li>For the cushion use the two short M3 screws to attach.</li></ol></li><li>Main Parts<ol><li><a href="https://www.youtube.com/watch?v=jz6_Hlkt3Rc&amp;t=4s">start with this video by sunlaki</a></li><li>Screw in the M3 screw into the sight to lock in place.</li><li>Place a double-sided removable sticker on each controller to solidly attach controllers.</li></ol></li></ul><h4>Remix Info</h4><ul><li>For “C_Body” part I eliminated branding allowing high quality-supportless printing.</li><li>For “C_Front” part I eliminated branding to smooth out handle.</li><li>For “D_Sight” part I added a M3 screw hole to fix loose sight in position.</li><li>For adjustable gunstock, increased M3 hole dimensions so no drilling is required.</li><li>The “D_Coupler” height impacts overall assembly heavily and since it's the weakest part you don't want to overtighten. I included two alternative parts that are +0.5mm or +1.0mm height. Depending on the pipe threading you may need a taller part.</li><li>For “E_Cushion” I aligned the part with the build plate correctly.</li><li>Grouping parts &amp; removing legacy components.</li></ul><h4>Source Models</h4><ul><li>The main source is <a href="https://www.thingiverse.com/thing:4538594">thing:4538594</a> by <a href="https://www.thingiverse.com/sanlaki">sanlaki</a> and he seems to keep links updated. My version is from 2021-03.</li><li>The adjustable buttstock is <a href="https://www.thingiverse.com/thing:4565145">thing:4565145</a> by <a href="https://www.thingiverse.com/slykittycat">slykittycat</a>, which is actually a remix of <a href="https://www.thingiverse.com/thing:4412938">thing:4412938</a> by <a href="https://www.thingiverse.com/Untangle">Untangle</a>.</li></ul><h4>Notes</h4><p>The <a href="https://www.thingiverse.com/thing:4538594">original on thingiverse</a> contains various videos &amp; a jillion extra notes. If you want left-hand controllers or parts for Oculus 1 go there.</p><p>The meshes for some of these parts are A+ and really clean, but the controllers and front coupler meshes look terrible so feel free to post a clean remix.</p><p>Blender forever.</p>
