Bernstein Soft Jaw Pads

prusaprinters

<p>The original Bernstein Spannfix vice has glued protective jaws. Although there are different versions, they all have to be re-glued when they are changed. Comfortable is different. Newer versions have a velcro system, but the velcro is a wobbly affair not suitable for precision.<br>Therefore, here is a variant to attach. Surprisingly, the vice is already prepared for this.<br>The first model is a version with vertical and horizontal prisms so that round objects can also be clamped securely.</p><p>With the little clamping aids attached on the top you can even clamp round items from out- or inside.</p><p>The pictures show a version made of Fiberthree F3 PA-CF Lite.<br>&nbsp;</p><p><strong>Hint:</strong> Fiberthree does not recommend this material for the MK3S, nor does Prusa have a profile for it. The reason is the flow rate of the E3D V6 hotend at 285°C nozzle temperature.</p><p><br><strong>But:</strong> If you have some time, you can achieve excellent results at low speed.<br>The 3mf contains my default settings for this material that was lying around after a mis-purchase. In the meantime, the spool is almost used up and there hasn't been a single misprint - apart from the many prototypes :).</p><p>For prints with other materials, the model may need to be adjusted, as the jaws are very tight and probably only nylon can withstand this tension.</p><p>If you still want to try it with carbon fibre reinforced nylon, I recommend the F3 PA-CF Pro, which can be printed with the V6 hotend at normal speed without any problems. Prusa Slicer has suitable profiles on board and the results are very impressive especially when printed on the fiberthree carbon bed.</p><p>If my limited time for this hobby allows it, I will add more variants. For those who can't wait, here is a step file to model yourself.<br>Surprise me with your Makes.</p>
