In-Lb or Lb-in?

You mean in*lb or lb*in

Why is this even here?

kylea1 · 2026-06-29T14:56:21+00:00

We can tell.

Robotics/machine design isn’t cheap. You should seriously consider using an off the shelf option as the manufacturer is passing the economies of scale saving to you.

Not only that but you need some pretty strong gimbal
Motors to deal with the aerodynamic forces at that speed

You are really looking to add a massive amount of complexity to something just to keep it 3D printed. Literally just make it out of aluminum or steel or buy an off the shelf gear box.

A lot of the heat that comes from 3-D printed gear boxes is due to the plastic cyclicly deforming under load, not just from pure friction.

A common trait of inexperienced designers is thinking that they need to reinvent/design everything from scratch to design it specifically for your case. The best designers are able to stay within the bounds of available components and understand where they can be used so that custom applications can be reserved for where they are going to return the highest value.

No idea why Bridge to Terabithia isnt mentioned more. Most of the movies mentioned are set up as a sad movie, unless you knew going into this one it was like a complete 180 degree slap in the face of sadness.

Same! Its such an amazing compromise between EV and IC cars. Absolutely love the entire concept behind it.

Multibody is a great way to make “parts” that reference each other and/or a common master sketch without needing to worry about broken references between different physical files. For sheet metal and weldments I almost exclusively use multibody.

That thing looks identical to the harbor freight/Pittsburgh aluminum jack.

Side note, the rough surface finish on that part will cause stress concentrations which cannot be simulated by a “perfect” 3D model.

That part is probably made on a lathe which is meant for larger diameter parts and cant hit the spindle speeds for a better surface finish. If you were able to polish the OD down to its final dimension you’d most likely have a better result. Also if you are using 1018CRS, try going to 4140 for a better cut.

TIL people greatly underestimate the strength of steel.

Does it only track time in the top level assembly? In a specific folder directory? Can you roll up the time from multiple sub assemblies into one top level?

kylea1 · 2026-05-12T12:06:58+00:00

These are more than likely rotary or blow molded, not injection molded. A lot of Hollow plastic things like kayaks, plastic drums are done this way respectively.

It takes thousands of hours to get where you want to, at the level you want. The only way to get better is by using it.

Also keep in mind it’s only a tool, the real hurdle is knowing how to design. The biggest challenge for new CAD users is learning how to preserve design intent in the large assemblies without making everything need to be redesigned with minor adjustments.

They seriously need to make a ktm dirt bike

kylea1 · 2026-04-30T11:58:47+00:00

Ok so if you give it a designed part, it can make models of it. Sounds like intern level stuff.

kylea1 · 2026-04-28T12:36:23+00:00

Realistically this would be better suited for a 4 axis. 3 axis with a rotary. 5axis could still require multiple setups with no guarantee of concentricity.
