Mini Pipe Vice/Vise

With the Hobbyist or Model Maker in mind here we have what think is called a Pipe vice/vise, the frame part would normally be hinged to accept long lengths of conduit etc but no need for that with this mini vice, good for holding round or square lengths of wood or plastic whilst cutting, I have put 4 countersunk holes in the base to secure the vice to a bench or piece of timber etc.I try to design these type of models so that there is no need for support during the printing process.I offset the threads on the main screw turn but there was still a little resistance and I had to work the thread clockwise and Anti clockwise to loosen a bit, this worked ok for me.To assemble the vice, slide the sliding top part of the vice up and into the main frame and then glue the main frame onto the base and leave to dry, you will need a 5mm x 8mm grub, this grub screw goes into the threaded hole on the slider and you tighten the screw until its seated in the recess on the screw thread, tighten this un
