How to build pib´s finger
pib’s finger consists of 5 printable parts and is assembled in 5 steps. For one hand, you should build 4 identical fingers – and one tumb (shown in separate tutorial).
Cut a piece of 90 cm length of the fluorocarbon string and insert it into D08 as shown in the picture.
Create a simple knot at the end. Pull the wire to be inside the circular hole and cut off remaining thread end above the knot.
At the end pull gently on the string to tighten the knot further.
Insert 1x nut through the shown hole in D08 (all the way till the end).
Our tip: use a small screw driver and insert it through the nut hole, then push the nut till the end of D08.
Connect D09 to D08 using 1x 16mm screw.
Insert D06 through the shown spot in D07.
Insert the D06-D07 assembly from previous assembly to D05.
Place 1x nut through the shown spot in D05 and fasten the parts using 1x 20mm screw.
Place 1 x M10 spring through the shown spot in previous assembly from step 3.
Insert the fluorcarbon string coming out of D08 through the shown hole in previous assembly (D05-D06-D07).
Use 1 x M08 rod to connect both assemblies.
Please note: it may be necessary to apply some gently force to push the rod through.
Insert 2 x M01 ball bearings through the shown spots in D08 and press on them till rod shows out and they are flush with D08.
Insert 1 x M10 spring into D05.
You did a great job!
