wonder if you could get the rotation simply using the tube in octagonal format

and because you are THE carbon guy!

And do away with the bottom plate, bolt through the deck with a thick washer on the underside to strengthen

That’s cool stuff. I’ve never seen these in person. How widely used are these?

Oh jeez, no idea. just goofed about on google for a couple of mins! I think they use are used in exhibition centres, but it is pretty specialist?

So, here is the update:

Yesterday piece was a bad print, today it’s slightly updated - smaller part overall, and closer to the final design. I’ve mounted one on an aluminum plate for testing, first off two things:

  1. there is a readily available endcap, so no need to reinvent it. Also, once adjusted, the 8020 profile can be cut as needed, this is the cheapest part in this whole thingy.
  2. you’re not going to give me hard time because of the slotted bolts, that’s what I had :slight_smile:

So, I’ve mounted this upside down, and stood on it through a belt: 20190425_125354 20190425_125544(1) 20190425_125544

Let’s do some calcs here: Let’s say we want to jump with a board. MTB board is ~20kg auw? So, 10kg per binding, let’s double it - 20kg per binding.

I’m 87kg and was completely standing on it before the belt slipped (can remove some material).

This is with PLA and 60% infill.

It’s safe to say - you’ve got yourself a binding design, I believe it’s sub 10$ minus the print.

Enjoy, Dani

And the baseplate?

I wonder if @Boardnamics could do a small run of the baseplate?

2 Likes

That too. Just have to finish it.

I have an access to water jet here, so I may practice cut several.

@danile what printer are you using for these prints? Also, that looks amazing!

Totally possible!

Thanks! Ultimaker2+

Wow! Nice printer!

The master at work, this is a really deadly design. Even though it’s thicc I would suggest PETG for final design as any ender peops can print & without getting into arguing that is stronger

Nobody wants a mount breaking mid-turn = accident

L brackets exist already for profiles, an L bracket at each side = baseplate
