Compact rod cutter attachment for Dremel flexi shaft

prusaprinters

<p>A compact attachment that screws onto a Dremel flexi shaft for cutting 5mm rod or tube. Use with a 38mm grinding disc or saw (saw not tested). I use it to cut carbon fibre tube. The two parts print in place without additional support. Unlike some other "Dremel chop saw" attachments which can only trim off a short length due to the body of the Dremel getting in the way, this attachment can cut anywhere.</p> <p>If you need a diameter other than 5mm, let me know and I'll see what I can do. Note that there is a hard limit to how big you can go with the 38mm cutter and the radial clearance available with the flexi shaft handle.</p> <p>Please be sure to follow all safety instructions that come with your rotary tool. Use of this attachment is entirely at your own risk!</p> <h3>Print instructions</h3><p>0.15 mm layers - important for thread detail and part separation after printing. 3 perimeters. 20% infill.</p> <p>PLA. Maybe PETG but I haven't tested if the parts will separate after printing.</p> <p>The two parts print in place without additional support, and then separate with a bit of careful encouragement. Use a 30mm long 3mm diameter bolt for the hinge. I used an M3x30mm hex head bolt, nylock nut and washers at each end, but use what you have to hand.</p> <p>Use an M3x10mm bolt in the other hole (see picture) to act as a depth stop. Adjust as required. The hole is intended for self-tapping. If it wears out, you can add a square M3 nut in the slot provided, but don't bother with the nut until the self-tap thread wears out.</p> <p>Please be sure to follow all safety instructions that come with your rotary tool.
