Slingshot wrist rest

prusaprinters

<p>This is a replacement wrist wrest for a Barnett slingshot. I think the model is a Black Widow but I am not sure. The strap which rests on the wrist when you are shooting tore and needed to be replaced. I got nothing from Barnett so I decided to make my own.</p> <h3>Print instructions</h3><p>This is in two "flavors" ... the simpler one is naturally quicker to print but the larger one is easier on the wrist. Both can be printed flat as the TPU bonds to itself very well, even in the triangular parts. The first print has the smaller one standing on edge, I don't recommend this as it fell over during the print. The result is still useable though, TPU is pretty forgiving. The pictures show the failed one, the gcode and 3mf have that one set flat on the bed.</p> <p>A note on printing TPU using the MK3S printer. <strong>BE SURE</strong> to loosen the extruder idler before starting the print. On mine I backed the tension screw about 1/2 way out of the nut. Without that I found that the TPU tended to warp inside the extruder and at one point wrapped itself around the gears. Removing the jam wasn't much fun.</p> <p>Filament: SAINSMART TPU<br/> Extruder: 225C<br/> Bed: 60C<br/> Supports: None</p> <p>I used the SAINSMART TPU stock profile from Prusa.</p>
