Description

20 years ago at my grandparents fishing cabin I saw this balancing sculpture of a fisherman trying to reel in a fish. The man never toppled over and could rock back and forth in a constant battle with the fish. Its been 20 years since Ive last seen the sculpture and couldnt find anything online to use as reference so I decided to try to recreate it from memory. And here it is! Enjoy!

The physics behind this model is that of center of mass. In order to achieve perfect balance, the center of mass of mass needs to be below the table and in line with the fisherman. In my CAD software, I used its center of mass calculations (with the material of the model set to PLA) to generate a coordinate system to show its location on the model. By adjusting the thickness, size, and location of the fish, I was able to gradually move the center of mass to the optimum location.

If you like this model and are feeling generous then please give it a boost! It would be very much appreciated!

GLUE POLE IN THE PLACE SHOWN IN IMAGE BELOW

FISHERMAN LEANING TOO MUCH OR OFF BALANCE?

If you notice that the fisherman is leaning too much then that means the pole isnt placed correctly. Add glue to the area shown below (2nd image) to adhere the pole to the fisherman. Make sure the pole is backed against the flat. Angle of the rod relative to the fisherman should be around 25 degrees. The angle of the pole will determine how straight the fisherman stands. High angles will throw off the center of mass.

loving this print. glue it if you the fisher standing up, or no glue to make the balance seem more unreal

@MeasureOnce

I have updated the model for better balancing. Also added a profile for multicolor if you want the fish in a different color than the pole and the man.

god

@Cprintz

I love the idea of putting him on benchys, I might just use that 😂

@cKBoy

could anyone help me out, I printed the man 3x. once including with the pole using the Bambu app(it failed to do the arms properly), 2nd, I printed using bamboo studio and took the pole out, spliced and printed (okayish print), 3rd print I just reprinted using Bambu app on my Android phone (failed again like the first)

@GnidaKid69

Doesn't look like a model has a problem. Are other prints fine? Honestly, I'm a beginner myself, so I have no idea what could cause this problem, but I would do the printer calibrations again. Also, ask on the Bambu forum or Reddit. People there should be able to help you.

@MeasureOnce

Was the fisherman getting pushed off of the plate? Because if so you probably are having bed adherence issues and should clean your bed

@MMPrinting

Looks like the filament is wet. Try drying it for a couple of hours then print again, or if you have a different filament on hand you can try that.

what type of witchcraft is this!!! Great job on figuring out center of gravity. worked perfectly when glued as you suggested

This one?

@MeasureOnce

Thats it!!! Oh man I havent seen that thing in ages

@CameraMouth

Replying to @MeasureOnce :

this is my dads. it’s older than 30 years for sure. it’s mine now. I’ll have to ask where he got this.

this was easy to print and works perfect with the detailed instructions from the designer, thanks! I printed another small boat as a base :)

@robertoouellet

Where did you take the small boat from?

seach unsinkable boat :)

cool design and print. haven’t glued it but just using it this way for now.

It was great but the print failed a little bit on the handle

@MeasureOnce

That sounds like it is an issue with your bed adhesion. You should definitely clean the bed with some alcohol and make sure you dont touch it. The grease from your fingers will effect bed adhesion. Definitely not an issue with the profile though

@MilesPrints

Replying to @MeasureOnce :

I'm sorry but it sounds like to me you have the issue, I'm sorry that you didn't understand. Even with a picture.

@MeasureOnce

Replying to @MilesPrints :

I am confused then. From the picture, it looks like the rod had an issue on the bottom layer (I am assuming bottom because of the build plate texture on the surface). If your bottom layer got dislodged from the bed then that means you are having adherence issues. I do recommend trying to reprint it after cleaning the build plate. You are the only person that I have seen with this issue so I dont believe it is an issue with the profile. Although it could also be the filament that is causing issues. Wet filament for example.

very cool

@MeasureOnce

If the pole gets loose then reprint the little guy with the file I just uploaded. He now has a flat on his hand that you can use to glue the pole onto.

didn’t balance

@MeasureOnce

Did you follow instructions and glue the pole to the hand?

@Andrewprints206

Replying to @MeasureOnce :

yes

@MeasureOnce

Replying to @Andrewprints206 :

Very odd. Just making sure, you didnt change any of the settings in the profile and you used bambu PLA? Because it should be perfectly balanced when the pole is glued in the place and at the angle shown in the description.

Really cool model and demonstration of center of mass. Thanks!

You forget to take the guy off when you turn the fan on… 💀☠️🏴‍☠️
