bobdea Posted March 23, 2019 Report Share Posted March 23, 2019 Anyone want to generate a file for me? Can’t even get the software to draw anything.... it would be no lift, no twist, just 3 degree cant. Just has to be wide Enough to accommodate the Now “skate tech” doohickeys. Screw holes set to accommodate 20-10 angles Quote Link to comment Share on other sites More sharing options...
JRAZZ Posted March 23, 2019 Author Report Share Posted March 23, 2019 I'd be happy to help but first, 5 hours ago, bobdea said: Screw holes set to accommodate 20-10 angles What do you mean? Quote Link to comment Share on other sites More sharing options...
bobdea Posted March 23, 2019 Report Share Posted March 23, 2019 It looks like if there’s no twist then the holes for the screws then they will be straight across the riser. Was trying to compensate for that. The software for customizing on Thingiverse would not even draw your specs nevermind when I tried to change it. So I couldn’t really mess with it. What I’m trying to do is build one that’s pure cant with as little lift as possible. Sorry to ask for the hand holding! I’m guessing the browser doesn’t like their website or something.

Think you can buy cant shims with asym washers so the bolts travel directly down into the inserts! Quote Link to comment Share on other sites More sharing options...
Corey Posted March 24, 2019 Report Share Posted March 24, 2019 I'll translate: Picture an angled block with 4x4 holes set so it can only be bolted on the board at 90-degrees (Skwal) or 0-degrees. That's what Bob DOESN'T want. He rides at 10 to 20 degrees and wants the holes to match so the binding has pure cant along its long axis. 1 Quote Link to comment Share on other sites More sharing options...

bobdea Posted March 24, 2019 Report Share Posted March 24, 2019 Ugh, won’t ship outside of Asia, those washers and screws were looking sexy! 1 hour ago, JRAZZ said: Ahhhh. I see.

bobdea Posted March 24, 2019 Report Share Posted March 24, 2019 ohhh! open scad runs WAY better on mac OS! I can actually see whats going on now without buggy rotation. okay, so here we go, just need to fix the screw holes and maybe some other small tweak. this is amazing! would your life be made easier to add slots (like the ones daveo posted) as opposed to trying to calculate the offset? I'm trying to learn open scad but I'm green to this...... 1 Quote Link to comment Share on other sites More sharing options...

JRAZZ Posted March 24, 2019 Author Report Share Posted March 24, 2019 So this still has cant across the binding and not along the axis of the board. If you want to get the canting axis along the axis of the board you need to do some "tweak-o-matic" math. Lift=sin(twist)*total_cant Cant_across_binding=cos(twist)*total_cant This will introduce a bit of lift that should (if I can still remember trig) rotate the axis of the cant to be along the axis of the board. Anyhoo, awesome let us know how they turn out! Quote Link to comment Share on other sites More sharing options...

dredman Posted March 27, 2019 Report Share Posted March 27, 2019 Hoof Cants modified and mounted. Was able to get rid of lots of stack height and all the little shim hardware with the F2 Titan Flex and mimic my TD-3 stance I have been using for a long time. 3 degrees square with board so a little toe and heel lift, little tipped towards each other. 1 Quote Link to comment Share on other sites More sharing options...

tpalka Posted March 5, 2023 Report Share Posted March 5, 2023 Resurrecting an older topic... but I'm excited because I just printed a set of plates for my soft bindings. Wish I could try them out today, but our local resort is closed due to high winds. Hopefully I'll get to try them soon. I'm new to 3D printing and this took a lot of learning. I traced the bottom of my bindings on paper, took a photo, drew splines in Inkscape, exported to Tinkercad, scaled to match real world dimensions. Printing in PLA was easy, but took me quite a while to calibrate live-Z to work with PETG. But it all came together, and at least so far the result looks good. I should have printed them 12mm high because of the limited sizes in metric bolts my hardware store has (printed shims instead). Used old bike tubes for the "elastomer" layer... A few other tweaks for V2, but after I put some hours on these. Ah, Rome bindings and a Stranda Shorty snowboard. The motivation was of course to be able to put it even more on edge, the board is really fun to ride. Tom. 4 Quote Link to comment Share on other sites More sharing options...
