A while back I was making a list for one of my paintings. I found it was not easy to make 45º wood conections so I decided to make a 3d printed tool for this.
I used one of my former designs of a small vise as a guide.
The main reason for making puzzle connections is that this design can be printed nearly twice as big as your printbed.
M8 bolt rod about 120 mm long (5/16 inch, 4,5 inch long) 2x
M8 hex nut's (5/16 inch) 6x
Single Endcap_V4 does NOT need to printed. It's optional for people who print only one base.
Insert the m8 nuts in place, use a solder iron to heat the nuts so that they melt in place and stay locked if the fits are a little tight.
I used 20% infill on the base and 40% on the remaining parts for extra strength.
some peaces needed a small brim to prevent warping.
