No problem, I'm 99% that hole is drilled there for that exact reason, just got lucky we can see the structure. 10mm higher and the structure wouldn't be seen, lol

I got real lucky then in this case! Definitely did not design with an impeding structure in mind.

Ummm… never saw this matte screen protector technique before. Adding it to the project list!

Thanks for taking the time to check for me!

I think you should be fine everywhere except the lower (2) rear holes. Right below that hole I have drilled is some structure. With the calipers flat, tons of room, angle them down ever so slightly and contact.

Amazing - thanks George Hill that's super helpful! good to know re the lowest holes. My thinking is to structural epoxy for the shear load with rivets to deal with any peeling load. So even if I can't hit those lowest holes it should be fine. Thanks for taking the time to check for me!

3) I got to installing the fender brace with these awesome new rivet nuts (definitely recommend). Fitting up:

Do you happen to know what the minimum clear air is on the other side of the bolt holes? I'm looking at riveting rather than bolting, but would need about 30mm of clearance to fully insert the rivets before crushing them. Wondering if it's clear air back there or additional layers of sheet metal etc. that might be in the way.

Also would the rubber resin grip the rotary encoder shaft well enough?

I’ll keep thinking on this as I think all printing methods are out for one reason or another. Maybe a tiny mold and pourable silicone or TPU would do it. Mold the soft stuff right on to a plastic center

Farm out is the plan. Looks like they're about $30 a piece or so. Am I crazy for considering just printing the whole thing in 60A rubber-like-resin?

Oof, thanks for sparing me the pain of that mistake. Now I'm trying to convince myself that this ABS plastic is good enough

Single data point, but my phone holder is printed in ABS and has seen many, many hours of direct sun. No warping or deformation that I can see.

Alright I’m happy with V3. Just 1mm shorter than V2 and feels right. Time to figure out SLA printing

Those look great

Just don't park the car in the sun! lol

Wow, I'm surprised at how different V3 looks to V2 after such a small change. Agreed that V3 is the way to go.

Gonna farm out the SLA print? Or new toy incoming?
