Sink bridge

thingiverse

A sink bridge to hold your whetstones when sharpening over the sink. It uses a 20x20 extrusion, I used a 45 cm long one but choose a length that is good for your sink. It also uses three 4x16 mm screws and t-nuts to hold the position of the blocks. It's a bit larger in dimension than it could be but it's very stable. Make sure your printer's dimensional accuracy is good as the holes for the extrusions are only 20.1mm, and also the hole for the screw can be a tight squeeze if you're over-extruding.
