Open Throw 2.0
Hi, I’m Scott, I know lots of you know me, I’ve been around the yo-yo scene since 1996, but I have never had something that I myself could personally contribute.
Until I got a 3d printer in 2023 and wanted to see if I could make a yo-yo. What I found was that there was very little in the way of free resources for creating playing yo-yos and the available options for bearing seats were unbelievably bad. So that was what OpenThrow 1 was mainly about. I put it up for a bit to work on other stuff but I had this idea for a v2 that added improved models to better support DIY yo-yos as a viable alternative to purchasing other people’s yo-yos.
Why openThrow and not [insertCompanyName]?
It wasn’t until I went to Indy States this year, that I was able to fully answer this question, but the three primary reasons are:
- I don’t want the player to be reliant on the availability of custom parts.
- I want the cost to be as affordable as I can make it, without sacrificing performance and only use off the shelf metal components.
- A customization standard, so that people who make their own designs can trade parts with friends and have them work.
When I learned about the Freshly Dirty Stem (and how awesome it is!) at Indy, I realized that each company is going to create their own parts and they will all be slightly different and incompatible, but generally had more in common than anything. So I decided to consider using manufacturer produced components as part of spec and will have “adapters” for a bunch of widely available systems, no vendor lock in.
So the machined parts are better than the printed ones?
No, well maybe. It’s going to come down to personal preference, but in terms of smoothness, the Self Sealing Stem Bolt system seems as smooth as anything as I’ve built with sid effects, Cabal, or FD stems… And only cost a dollar per yo-yo with parts you can get on amazon.
What playstyles will be actively supported?
All of them. Today I am announcing the availabily of 1A and 0A example models*, but I have prototypes (yes, more than one, actually, three distinct kinds) for 2A. You can find one of the prototype elements in the 0A model, but it’s not quite right in the current form.
*All models can be either responsive or unresponsive and even hot swapped for looping responses.
Gimme!
0A: Runabout
0A - Modern Responsive “Runabout” keeping with the DS9 Trek theme, the pre production was called “The Scout”.
1A: Synestia 2
V1’s demo model was called the Synestia and the followup made sense to have the same lineage since the first one didn’t really live up to the name
1A - Unresponsive “Synestia 2”
