Fork Clamp for vice, Ducati 56-57-58 mm
Description
8/29/20: UPDATE. Discovered my forks have 3 distinct diameters. Redesigned the vice clamp to accommodate all 3 diameters. Also added another set of "wings" so the clamp can be used to hold the fork tube horizontally. New version files added to this thing as V3. V3 has smaller thickness "springs" to allow easier movement of the 2 halves. V3 also has 4 cylindrical protusions that actually engage the fork tube, allowing the varying diameters. Printed V3 with 6 perimeters and 25% infill in PETG. 56mm fork tube clamp for vice. No-mar clamp for holding fork tube while servicing fork. STEP file included so you can remix whatever diameter you need. Clamp rests on top of vice jaws, lips prevent it from falling out. "ears" have enough flex to compress when clamping. I printed in PETG with 7 perimeters for compressive strength. 4 holes give strength in direction of compression. Update 8/26/20: I used 7 perimeters and a 25% infil. I added a cutaway slicer view to the photos. With this setup, the 4 holes give a "push" compressive path from the vice to he tube. The 25% infill is just for some stability of those 4 holes and for when the tool is not in the vice 100% as shown in the photo. Consider if it were a solid plastic block: When the fork clamp is compressed in the vice even with a perfect fit on the tube diameter, the pressure will occur mostly right in the middle of the tube hole if the block flexes at all. With an infill (not solid) that flexing will be more pronounced. So my intent was for the 4 holes to be little ridgid cylinders inside, so now when compressed, they compress the least and thus put pressure on 4 quadrants of the fork tube. Hope that makes sense. Anyway, important to do enough perimiters to attach the 4 hole's walls to the exterior clamp's walls.
