Ahh yes that makes sense, in theory you should have an opposed action like that with something securing it but I think my brain is predisposed to janky stuff like this:
You only really need to hold onto the bottle and have an upward force

I could definitely draw out a design like that and have it lazer-cut, but I went with my design for a couple of reasons:
I dont personally feel that the brass-knuckles style grip would be very comfortable to lift 50 pounds.
I wear pretty thick gloves, and so sticking my fingers in those holes might be more awkward, which reduces the convenience of the handle.
Etoxx is an expert machinist, and makes beautiful CNC’d parts where every corner and edge is nicely rounded. I am going for something very cheap here, which means lazer-cutting. That brass-knuckles style design I think would be really uncomfortable with sharp lazer cut corners in every hole.
With my current design it’s easy for me to model and print a soft, comfortable TPU grip that snaps onto the handle, but I couldn’t do that for the brass-knuckles style design.
gotcha, all very valid points, just personally I think the BN grab would actually be easier on the hand but that’s just my thoughts as I haven’t tried either.
You might be right when comparing bare metal to bare metal, but when you add the TPU grip on my design to the comparison, I feel strongly that mine will be a more comfortable grip Though of course comfort is all subjective.
Another note about the brass-knuckles style design for eMTB grab handles:
Is it just me or are they always upside down? Like, when holding brass knuckles, the holes line up with the natural curve of your fingers, so your grip is like this:
I just ordered a de-burring tool to test out. If it works nicely and isn’t too much work, then I’ll consider doing that to the production units. I am trying to avoid post-processing as much as possible, because I simply dont have the time and I want to keep these cheap. But if this is simple and quick then I’ll probably do it, cus I want to sell nice products.
Also went on a sweet ride yesterday around Portland with my buddy Liam. The handle is awesome, makes moving the board around so much easier! It seems to be rock solid so far, no sign of it bending even when I am lifting the board completely off the ground with it. I tested out putting most of my weight (225lbs) on the end of the handle, and it didn’t bend.
Really glad I had my DuckGripz today, dragging my board back to the car would have been much worse without it. I really need to get that TPU grip printed though lol.
Ok so I am really bad with a de-burring tool. I could probably get better with enough practice, but I dont think that the time I’ll spend is worth the very dubious improvement.
I’m going to just focus on the TPU grip and making these as cheap as possible. Full steam ahead!
P.S. if anyone wants to draw up a 2D dickosaurus (preferably a vector graphic, but any line drawing works) then I’ll make a dino-dick version
