Heyho
For the MakerFaire in Hannover I did need some tools for the visitors to thest the laparoscopic trainer.
https://www.printables.com/model/864261-laparoscopic-trainer-for-students-and-surgeons-col
Sadly the tools my friend Allen Mehr sent me from Hawaii didn't arrive in time. So I had to spontaneously create these grippers :)
They make the whole process of learning how to coordinate and grip stuff on the laparoscopic trainer a lot harder! At the faire I offered the visitors to unwrap some candy with them. It worked very good but it also was quite a challange!
So if you want to train your coordination skills, you just want to have a cool party game or need grippers like this for any other task: Here are the Dragon grippers for you! :D
In addition to use this Grippers on the Trainer you will also need to print the ball head with a 8 mm diameter hole. (Extra .stl in this design)
Print Instructions:
I used PLA & PETG for the Parts. 3-4 Perimeter and 100% Infill for best stability.
0,2 mm layer height and 0,4 mm nozzle.
Parts List:
In addition to the printed parts you will need:
1 x stiff rope (mac 2,2 mm diameter)
1 x Carbon Rod (Outer diameter 7,35 mm) I used the Warrior Arrow shafts by bearpaw.
The length of the rod and rope is up to you. You can create a short or a long version of this gripper :)
If you need the design for annother sized tube: Ask me directly or comment the desired size. I might have the time to adapt the design to other sizes!
1 x M4 x 10 mm Screw (Handle)
1 x M4 x 8 mm Screw (Handle: Rope fixation)
1 x M4 x 10 mm Screw (Pulley)
1 x M3 x 18 mm Screw (Dragon Head)
1x Rubber Band (Not too strong - just to keep the mouth open when there is no tension required)
Assembly:
See the assembly of the parts in this picture!
Have fun!
