Machinists V Blocks

thingiverse

Machinist V Blocks. The larger of the two will hold a maximum of 50mm (with a 6mm clamping screw) and the smaller one 36mm (with a 4mm clamping screw). Print near-solid if you want to get the most out of them but bear in mind that 100% solid 3d printed parts can be susceptible to over extrusion and warping which could destroy their accuracy. I found that 60% infill worked well on my Anycubic I3 Mega and the blocks are still pretty durable.
