Tapping Jig for 3030 and 3060 Aluminium Extrusion

prusaprinters

<p>Making it easy to tap and make holes for the key when building out of 3030 and 3060 extrusions.</p><p>It uses a 608ZZ bearing on the tap part and a 626ZZ for driling holes. This way the drill does not drill into the jig.</p><p>I used a "Völkel M8 Fluteless machine tap". This is a roll tap that doesn't cut but form the material. I couldn't get a normal cutting tap to work on Misumi extrusions.</p><p>I used M8x20 screws with 5mm hex key. The holes are therefore 6mm but I had to enlarge them later to 7mm because of missalignment when using the drill.</p><p>I used a HSS drill to drill the holes.</p><p>Don't forget to use lots of cutting oil!</p><p> </p><p>Fusion 360 files included for you to modify.</p><p> </p><h3>Print Settings</h3><p><strong>Resolution: </strong>0.15</p><p><strong>Filament: </strong>Cheapest noname PLA </p><p><strong>Notes: </strong><br/>No supports except for on side holes for "DrillJig Middle".<br/>Printed with 5 walls 0.4 nozzle and 6 top/bottom 0.15 LayerHeight.</p>
