I’ve been diddling around in Fusion and I think I’ve finally hit on a somewhat decently functional design for a motor mount. It’s pretty heavily inspired by the Boosted mount which IMO is absolute design porn. It literally slides on snugly and is held in place with 3 grub screws (and probably some epoxy).
Anyway, they’ll allow you to mount dual 5065 motors (racerstar, probably Ollin too) with 15mm belts - just as a note, you’ll need ~50 degree trucks and 60mm+ axles for this.
They’d probably be less than $50 for the pair and anodised black (unless you have a better colour suggestion ).
The first prototype - around the truck-mount connection the material was far to thin, and the truck holes were orientated 45 degrees off.
The test 3d print, aside from shrinkage and me not being able to orient motor holes correctly , came out really really well (sorry about the shitty lighting in my house):
I don’t think that’d be an issue… The grub screws provide an opposing force to the shake off force. Also, using epoxy to form a semipermanent bond like lock tight would probably be enough on its own
I’m not the biggest fan of how his mounts extend the wheelbase to like 300mm, these only extend it to 220mm.
Thanks for the input, I’ll fiddle around a bit more and see if I could maybe wedge the mount to lock it on
Touché. Isn’t it 260mm? 200+(80-50)*2. I was pretty off with 300mm so I apologise for that
@torqueboards seems to have had success with grubs as that’s how his latest clamps are held on. How could I improve my design then? I tried the whole clamp thing but it doesn’t really work.
I had an older version with clamps but when I printed it it the walls were a bit thin. I’ll try bumping up the diameter a bit and adding mount holes… brb
@thisguyhere and @Colson003 thanks so much for the input!
It now clamps onto the truck and locks around bend in its profile. Do you think this’ll be enough to hold it on?
The manufacturer I was going to go through (I’m using them for my hub motors) said the part was bigger than they’d normally produce… pity
But hey, if you want the cad files pm me and I’ll email them to you
