Man I love CAD/CAM programs. I can’t wait to actually take a class and really learn how to do stuff.

Is that UHMW?

What material is this? I’ve got a clip I need somebody to remake for me in a durable, yet flexible plastic at some point, haha! :P

It’s UHMW. It’s pretty cool stuff. Wet got a shit load of it lying around. I could send you a piece.

Lol sorry didn’t see the remake part of the comment. Depending on what it is, this could be arranged.

Yup! It’s 10x30x3

Lucky guess, all those natural colored plastics look the same in pictures to me. What program do you use?

It’s a clip to mount my snowbrush to my parcel shelf in the winter that I 3D modeled...a fellow Opponaut 3D printed a pair of them for me awhile back, but one of them broke, sadly....it would need to be a flexible material though! Not big at all, and I have an .STL file for it!

I will see if the program I am using can open an .STL file.

IT CAN OPEN IT! This is exciting!

Also UHMW is flexible if the piece is modeled thin enough where the brush pops in and out.

OneCNCx2. It’s the only thing we have and I am self taught so there is a lot i don’t knows how to do.

Coolness! If it wasn’t too expensive, I’d pay you for printing a pair and mailing them to me if you’d be willing! :)

I’ve got no CAD experience, but I have made a number of things in Sketchup (which is where I modeled this). I can re-use the nut-caps I have now as they aren’t damaged, but getting the clips made in a sturdy material would be nice! The part where the brush fits isn’t very thick, so it should be OK I would think? I’ve had it printed in PLA and ABS...the PLA warps in the summer heat and ABS would be fine, but it wasn’t printed with the layers close enough together to make it sturdier, so one of them cracked between layers in the cold the other day. :(

There’s a link to some pics of how it mounts/looks/works and the .STL file if you wanted to try loading it to see if your program would open it! :)

I can see it! The scale is way off but I can fix that I think. Is that 51.8 mm in the other picture correct? I work in inches so I will convert it.

Yup - millimetres! :)

Okay I got it re scaled and in inches. I have to alter it some. I can’t do alligator teeth like it is but I can do something similar. I will also be adding in some radiuses that weren’t there because I will be using end mills. Also do you want that boss on the back like in the picture for the screw to thread into? How thick is the part of your car that the alligator teeth go on? The wire frame for the clip was crazy.

 This is not the complete drawing. I will send you a final drawing for you to approve before I mill it out.

The wire frame was probably nuts because it was originally a Sketchup file I converted to STL using an open-source plugin for Sketchup.

Although...one moment. I just noticed there is a web-based Sketchup update that seems to be natively export to STL now, so let me go see if I can get a cleaner file for you.

The teeth are there to help to keep it from moving around as it’s clipped over a ‘fuzzy-ish’ parcel shelf (as in the top side has that weird ‘fuzzy’ material to it), so something similar would be good!

Not sure what you mean by the ‘boss’ (forgive my ignorance!)? If you mean the hole that goes through the ‘alligator teeth’ end of things, then yes - a screw threads through there and I have 3D printed ‘screw caps’ I can still use to cover the pointy screw tips as the 3D printed ‘screw caps’ never broke.

As for the thickness of the part it screws through, the thickness of the part is about the thickness of the width of the alligator teeth, but SLIGHTLY thicker...enough that the teeth have to bend around it, though the screw tightens them together. The screws are just long wood screws, but they have to be able to thread through the clip (as in actually work threads into the material of the clip).

Hope that all made sense! :P

Should be an updated STL in the GDrive folder with ‘UPDATED’ added to the front...no idea if it’s cleaner or not...

Well from what you just said I thing I can make the teeth work. Also do you want new caps? If not than I will just drill the hole as specified. If I make caps I could provide you with new screws. Also do you know the diameter of the snow brush’s tube? I got multiple diameters when I initially made that line drawing. I won’t be able to work on it anymore this weekend but i will continue on Monday after work.

By the way, i am super enjoying working on this. It’s nice to have something that is not work related to work on. : )

Well, as mentioned, as long as the material is able for me to manually thread a screw into it, new caps would be nice, but my current ones are not broken so I could still use those (I have a file for the caps as well).

I can re-use the screws I have, they should be fine (I’ve had two 3D printed iterations of these clips now and have used the same screws through both, so they should be fine for this pair).

No rush, so no worries on the weekend thing! :) They are just nice to have mounted in my car...you’d be surprised how nice it is not having a snow brush rattling around in my trunk or interior during the winter and summer months, and they get it up and out of the way, but still in my car during the summer! :D

As for the diameter of the brush...I don’t have measuring calipers, so the best I’ve done is hold a ruler up to the brush and guess...which is what I did with the file you’ve got. For the record, the width in the file I sent you was damn near perfect for the brush to snap into, surprisingly. I’d used 23.3mm (0.917 inches) for the brush diameter last time...but keep in mind that was the DIAMETER, and the open end of the clip has to be LESS wide than that for it to snap and and hold properly. The open end of the clip I’d used before was 19.7mm (0.775 inches).

Glad you’re enjoying it....it was fun to design it in Sketchup when I had first tried and it’s neat knowing something you designed is actually useful, haha! I also designed the wheel caps on my current summer rims...they are ‘98 Ford Escort rims, but having ‘Ford’ on them seemed odd considering I drive a Hyundai, so I made new Hyundai ones to be more fitting! :D

Awesome! Also I NEED “TURBO LAZER 4" tires! That’s the best name ever. Having the diameter helps a lot. I will keep you posted.

Haha, it is the best tire name ever! They are Motomaster, which is a house brand of Canadian Tire here in Canada....Turbo Lazer 4s are actually an older model, so you can’t get them anymore, but they are an all-season rated for Mud and Snow. :P

Will keep any eye out! :D

I’m self tought in CAD, I’ve never done any cam stuff because I don’t have a CNC machine. It’s something I want to try though.

Just want to give you an update on where things are. I started going back to school last week and it had screwed my schedule and my weekends up. I haven’t forgotten about you, I just haven’t had to time to work on it. Sorry. :( I feel bad about this.

Okay, so here is where things stand,

For some reason I can’t add comments to the photos but, the top one is final drawing. Middle is computer simulation. Bottom is final program for the piece. I plan on making them tomorrow.
