Its On My Mind

I added three small manual supports inside the linkage area to ensure clean bridging—remove them after printing.

This Print Profile comes with 50bb&#39;s. It includes 3 wall to insure the spring and mechanisms do not break from use. It also has infill adjusted from 40% to 20%.  It works as good as the original!

单盘单色打印，请不要改变该打印配置的模型摆放角度，以免接缝位置与预期不符。 修复多处可能造成缺陷的悬垂和桥接，详见下方。不建议在同一盘添加 BB 弹，这会更容易导致打印失败。 工艺参数可用于 PLA 和 PETG。当前耗材参数为 PETG HF，请自行修改为你校准过的耗材参数。 无论什么模型，始终建议打印前清洁打印板并适当涂胶，避免模型翘边、脱离导致“炒面”。 修复问题如下：<ol><li>推杆存在悬垂结构，并且其与打印板的接触面积非常小，所以降低推杆的打印速度，减小其脱离打印板造成打印失败的可能性。</li><li>通过添加小的负零件、旋转模型等方式调整接缝位置，使四个关节悬空打印的起始点都位于零件内或支撑上面。</li><li>因为原始的切片参数中桥接的起始点与两端的接触面过小，此处的桥接非常容易出现缺陷。通过绘制接缝使内外墙的起始点位于中间位置，增加桥两端的粘附。从评论区分享的图片也看到此处存在缺陷的情况。</li><li>还有一个比较特殊的情况。当桥接与旁边的顶面在同一层打印时，如果两者距离非常接近，“内墙/外墙”的墙顺序就无法正确表达，这会导致桥接的粘附更差。通过添加部件抬升顶面 0.1mm，使顶面与桥接在不同层即可避免该问题。实际上此处原本的 1.1mm 沟槽也无法在 0.2mm 层高正确打印。</li></ol>

Single-plate monochrome printing, please do not alter the model's orientation in this print profile, to avoid misalignment of seams. Multiple overhangs and bridging prone to defects have been corrected, see below. Adding BB pellets to the same plate is not recommended, it will more easily lead to print failure. Process parameters are suitable for PLA and PETG. The current filament parameter is PETG HF, please modify it to your calibrated filament parameter. Regardless of the model, it is always recommended to clean the build plate and apply appropriate adhesive before printing, to prevent model warping, detachment resulting in "spaghetti". The following issues have been addressed: <ol><li>The actuator has an overhanging structure, and its contact area with the build plate is very small, so the printing speed of the actuator is reduced to minimize the possibility of it detaching from the build plate causing print failure.</li><li>The seam position is adjusted by adding small negative parts, rotating the model, etc., so that the starting points of the four joints' overhanging prints are all located inside the part or on the support.</li><li>Because the starting point of the bridging in the original slicing parameters has too small a contact surface with both ends, defects are very likely to occur in this bridging. By drawing seams, the starting points of the inner and outer walls are located in the middle position, increasing the adhesion at both ends of the bridge. Pictures shared from the comments section also show defects in this area.</li><li>There is also a more special case. When the bridging and the adjacent top surface are printed on the same layer, if the distance between the two is very close, the wall order of the "inner wall/outer wall" cannot be correctly expressed, which will lead to poorer bridging adhesion. By adding a component to raise the top surface by 0.1mm, the top surface and the bridging can be on different layers to avoid this problem. In fact, the original 1.1mm groove here cannot be correctly printed at 0.2mm layer height.</li></ol>

Fixed overhangs and bridging prone to defects.

Just a simple bb-insertion-hole cover for the gun, because I found that if i tipped the device, bbs flew out sometimes. I hope some people can find this useful :)&nbsp;All you have to do is carefully remove the supports, then it should snap on easily. Make sure to put it on the same way I have in the pictures on this profile.

Linkage Launcher With 20 flat bottomed BBs to avoid brim. This does not affect the functionality and the BBs work just fine. ;)

<figure class="media"><oembed url="https://www.youtube.com/shorts/4MaoS_6WvVM"></oembed></figure>This is a spring-powered BB launcher featuring a unique 4-bar linkage mechanism with a single compliant spring for reset. It’s fully 3D printed in one piece—no assembly required. The integrated high-capacity magazine includes a slotted grid that shows how many BBs are loaded while securely holding them in place. Despite the complex geometry, everything prints cleanly without supports on a well-tuned printer like the Bambu X1.
