If your printer struggles with printing straight bridges, pre-supported versions of each base are available. Just use a screwdriver and hammer to gently knock the custom support out after printing.</p><p>The spring works best if it's printed with enough perimeter lines to make the arms of the spring solid. This works better than just increasing the infill % because perimeter lines will flow in the direction of the spring arms.</p><h3>&nbsp;</h3><h3>Assembly</h3><p>Assembly is the same as the original <a href="https://www.prusaprinters.org/prints/81786-twist-lock-trick-box-hexagon">Twist Lock Trick Box</a>. Watch <a href="https://youtu.be/1muiuHjyLlU">this video</a> for the complete process.</p><p><strong>Make sure to pre-tension the spring by one gear tooth</strong><br>This will assure that the latches have a strong hold on the base. This is also necessary for the alignment of some toppers.</p><p><strong>Make sure to glue the spring and topper</strong><br>If you do not fully secure these parts, the mechanism may become detached while in a locked state. I recommend using either super glue or <a href="https://www.3dgloop.com">3D Gloop!</a>, but hot glue can work as well.</p><h3>&nbsp;</h3><h3>Internal Dimensions</h3><p>Approximate internal space for each box.</p><p>This doesn't include extra space available in the corners and lid.<br><br><strong>Base 38mm</strong><br>180 x 180 x 38mm</p><p><strong>Base 68mm</strong><br>180 x 180 x 68mm</p><p><strong>Base 98mm</strong><br>180 x 180 x 98mm</p><p><strong>Base 128mm</strong><br>180 x 180 x 128mm</p><p><strong>Base 158mm</strong><br>180 x 180 x 158mm</p><p>&nbsp;</p><h3>Can I sell copies of this?</h3><p>Yes!
