Stainless 8mm rod straightening

thingiverse

I made this DIY solution because my ordered new rods didn't show up in the mail. So I had to come up with a plan on my own. This is a pretty straightforward concept: just use 608z bearings and snug them into bearing holders, then mount those into a piece of wood or plywood. Next, slot an 8mm bent rod into place and use a pen holder to mark the area that needs correcting. Rotate it as needed to check the marks. You'll have to do this visually and bend the rod manually with your arms for at least 12-15 seconds before checking again. Since I don't have any gauges, this is the closest I can get the rods to being straight. Make sure to print two pieces of bearing holder. Required items: * 2 PCS 608z skate board bearings (they're 8mm) * Some plywood or MDF at least 10-12mm thick * Some wood screws, 20mm long and M3 size x6pcs
