Vise

This is a remix based on Trucking and McMosfet designs. It is custom matched to my Delta drill press but I rebuilt all printed parts in Onshape. These parametric files are available via this link (you need to have at least a free account):

The assembly is updated to use all english hardware:
Part Qty
⅜-16 x 8” hex bolt 1
⅜-16 hex nut 2
¼-20 x 2.75” hex bolt 2
¼-20 hex nut 2
8-32 x 1.5” round head machine screw 4
8-32 hex nuts 4

I printed all parts on an Elegoo Neptune 4 Plus printer using a 0.4 mm nozzle and PETG.

The design works very well to hold small modeling parts I work with.
