I extended the bottom part to make it fit my table, and also added some isolation rubber (the one you buy for windows) to pad the bottom which was too slippery for my surface and the screw whose edges where a bit sharp.
I had some problems with Vise-2 and the screw hole, as the hole it appetite be just a bit too small and made the clamp to crack. Was it just me or anyone else got the same problem? I might reprint it enlarging the hole by .5 mm.
I also have printed it in PLA which possibly is not the best choice
