Description

I was just playing around with printable trapezoidal threads and before I realized it, I had designed a large machine vise…
The vise has a clamping range of 120x120mm. It is good for circuit boards because plastic is non-conductive.

Standard trapezoidal threads (30° thread angle ) or ACME threads (29° thread angle) are very difficult to print in an upright position. The overhangs are not supported by the thread geometry. Therefore my thread has a thread angle of 42°. This can be printed upright at 0.12 layer height without using supports.

Print all threaded parts in an upright position with a layer height of 0.12mm or smaller. All other parts can be printed with 0.2mm or bigger layers. Support is needed for the Slider and the Jaws. For the Base support is optional but recommended. The other parts do not need supports. I am using 4 walls, 5 tops, 4 bottoms and 10% gyroid infill. See my 3mf file for more details and change it to your needs.

Due to the complexity of the parts I do not think that printing directly with Bambu Handy is possible. Better use Bambu Studio .

Just to mention it - this is a large vice. It needs more than 0.5kg filament.

The gap between the parts is 0.25mm for all movable elements. The pins have a smaller clearance (0.15mm) as those are a press-fit. If necessary they can be hammered in position. I was using some very cheap filaments that had large tolerances in diameter. In that case you might need to rework the holes for the pins with a drill (Ø4mm) and sand the sliding surfaces evenly. This should not be necessary if you use quality filament. For the sliding surfaces and the thread I am applying candle wax as surface treatment (just rub it on). Then you have a nice and smooth vice action.

Strength Issue:Due to the settings of the print the threaded rod snapped i had to drill the pins out due to them being put in place and reprint the rod with full infill and reprint them all all you need to do is reajust the file for the rod to be stronger by increasing the infill

This vice works amazing! I printed the threaded rod out of PLA-CF and it's very strong. I use it for hand sanding knives and it works great.

schöner Schraubstock. finde allerdings dass der Schlitten ein wenig zuviel Spiel hat. Vielleicht wäre was einstellbares besser gewesen.

great stl file. I’ve printed with bambulab p1s and for the sceew it’s important to reduce speed. It failed twice time and it worked fine after reducing speed

fantastic print. my first interaction with supports and bambu breakaway support PLA. I ended up adding some food safe grease to the lead screw and inside channel to make it quieter and move for easily. Testing the limitations of my first print I ended up breaking the lead screw. was a simple reprint at 5 Wall/80% infill for the replacement with a couple new pins too to replace the ones I had to drill out.
