<div dir="auto">That's a good point. 3D printers operate in metric mode, as do modern CNC machines. Anything created in imperial units gets converted to metric under the hood, with occasional rounding errors. I do all of my designs in metric now. Joe would shudder.<div dir="auto"><br></div><div dir="auto">I have a nice assortment of M2-M6 screws, nuts, and bolts, but sometimes I'll adjust the design slightly in fusion 360 to use imperial hardware.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Jan 16, 2021, 9:42 AM indigogyre <<a href="mailto:indigogyre@gmail.com">indigogyre@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="auto">Hello,<div dir="auto"><br></div><div dir="auto">As a side note about printed items.

This was printed in ABS, so it prints a little slower. ABS is needed because PLA or PETG could shatter if it came in contact with the blade, which nullifies the use of this.

If you have a good printer, the size is correct. On the knobs, I may have to add some epoxy at some point, but for right now they seem solid with the bolts just pressed in.</div><div><br></div><div>The biggest hurdle is that this was designed in France, so it uses metric hardware. M4 + M5 nuts and bolts. I got mine on eBay for fairly cheap from a US based supplier. You can also get these on McMaster Carr for cheap enough, and probably a little higher quality.</div><div><br></div><div>The "grip" I just use old mouse pads, glued on with rubber cement. I got a stack of these from work years ago, and am slowly working my way through them, but you can also find them at thrift stores or garage sales sometimes.
