Tension adjustable fitting – Photo hanger

I made this to hang photos – it could be used for any purpose though. I fixed the base to the wall using 3M double sided tape.

One end if the string is tied to the fixed “base”. The other end is tied to the bolt after passing it through the hole in it. Adjust the tension by turning the bolt, pushing it into the slots (on one side of the base) and tightening the nut on the other side.

Printing tips :

• I printed the “fixed” base at the highest speed I was comfortable with (0.2mm).
• The other base was printed at a lower speed (0.2mm Quality on Prusa)
• The nut/bolt was printed with a lower layer heights of 0.15mm.
• Did not add much infill for the nut (15-20%).
• The bolt had a 50% infill. I added a 100% infill region near the hole in the nut.
• I needed 2 pairs. The print was done in 3 sessions : 2 base, 2 “fixed” base, 2 pairs of nut/bolt.
