Here we have what I think is called a Corner clamp or Angle Clamp, anyway it's for clamping 2 pieces of wood or anything really like picture frame corners etc etc whilst they are glued together.
I saw an image of one and I thought now that looks like an interesting model to design and print and I'm guessing due to the size it would be very useful for hobbiest's or Modeler's/Modeller's.
You are going to need some hardware for this model, 2 x 5mm grub screws or Allen bolts to tighten onto the screw adapter and 1 x 5mm flat head allen head bolt approx 15mm to fasten the screw adapter to the screw, much like a lot of my other vices I have uplaoded.
Quite a challenging model to design but great experience with the design software I use.
This is one of 2 models of this nature so please take a look at the MkII models as well.
No support needed when printed but one thing to note is that I printed the screw threads separately as I printed them at 100% infill for additional strength, thats 100% Rectilinear.
Thanks for Looking.
