Description

Sailing Block & Tackle used for 3/8" lines (or similar)

Boost Me (for free)

I will continue to provide quality sailing and other functional prints!

FYI… Rig tested with ASA up to 200lbs so far without failure.

Bill of Materials (per Block):

Stainless M4 x 12mm (x2)
Stainless M4 Nuts (x2)
Stainless M8 x 60mm Hex Bolt (x1)
Stainless M8 Nut (x1)
Stainless M8 Washers (x4)
608RS Bearing (x4) (https://a.co/d/ftNG3Js)
Stainless 3/8" Pad Eye Loop (https://a.co/d/7pYelT7)

I prefer all stainless parts because I am using this on my sailboat, however use whatever you like at your own risk!

PA6-CF would be best choice to print for strength and elements protections.

My prototypes were made out of ASA (parts in teal) and TPU 95A (green)… they are pretty damn strong!

I have bearings in order still but I’m excited to test. Print came out great with black ASA from Bambu. The white is Bambu TPU for AMS.

Awesome dude, thanks for the post! Wait to you see how crazy strong it is once you add the hardware - i lifted my girlfriend and a bunch of weights I was that confident in it haha

Replying to @ipeeks :

@ipeeks Any thoughts or tips on printing with ASA? I’m using an X1C so I have no chamber heater. This snapped when a coworker was playing with the print and testing it’s flexibility and of course it sheared at the part with the least surface area on the print. 😅

@ipeeks

Replying to @printosaur :

That is so interesting... your print seems to have small defects mine did not (almost like air pockets?), maybe its just too cold? I used PolyLite ASA. Try reprinting the part on a diagonal and slower? Also how the hell did he break it? My buddy was swinging from this thing with a rope.

Printed perfectly! The perfect model to try a 3d printed block and tackle, printed the body in ASA, waiting on Amazon for the stainless hardware!

I am so excited for you to try this out, I was really impressed with how strong it was... After some testing, I pulled my girlfriend up our backyard tree with that setup. Not recommended, but she is a little crazy and trusted me... worked flawlessly 😂 FYI... the stainless loops from Amazon are not all sized perfectly, however if you use the link I provided and buy that exact one you will be able to make them work. Make sure to start both sides loosely to get the fasteners in the holes, then once in, you are good to go!

@TheDarkMat

Look, I get that you may have tested this but you are putting force against the layer lines. This is an accident waiting to happen. Forces should always be experienced along the layer lines, at their strongest. Your other designs were better because you'd print them flat and then use the vertically. This is my analysis from the images you provided alone. I can't see myself printing this because of this design flaw. I'll stick to the 4.1 for now

The designer has replied

@ipeeks

I would suggest printing this on a slope to give an angle to the layer lines, the first print was a prototype. However the hardware being thru bolted is doing a tremendous amount of the heavy lifting. I don't disagree with your analysis, however I would just modify the print angle on this design, I find it superior in general.

@TheDarkMat

Replying to @ipeeks :

As the old saying goes: "you're only as strong as your weakest link". The fact is that for general applications this is probably good enough but I tend to push things to their limit so I'm to be very picky about the robustness of the design. Looking forward to seeing the next iteration!

@cdn_bacon

Why use TPU of the sheaves?

@ipeeks

i didn't?

Great model. Can this one be expanded for 3 wheels?

Great design, thanks for making it!

@leah_leah

Different sizes of these would be amazing - especially a tiny mini one.
