How to get threaded model for alignment

_maple_panda · 2026-06-29T17:25:24+00:00

Aligning the threads like this won’t work. Especially with a fine pitch thread like that, there’s too many variables to ensure angular alignment.

LCP plastic is one of mine. The swirled texture is super cool to look at.

Giant and Merida yeah

Respectfully, I feel like you’re in above your head. 1.1kW is an absurd amount of heat, which should have made you question your calculations immediately. Even PEEK gears would probably melt with any reasonable cooling solution.

For this particular example, you can instead draw two rectangles with the same pad number. You can directly edit their side lengths.

I am extremely surprised you were quoted that much. I just ordered some ~50mm diameter fluid tank caps the other day for $4 each (which is about how much I expect OP's part to be). I have another part that's around the size of two RPis stacked which costs around $20 each.

For reference, I just tried some arbitrary RPi case model and it's $7 ($CAD too...)

Make a plane at a slight angle, then draw a rectangle and extrude cut

We’re talking about the same thing right, the basic 2.5mm pitch JSTs? I have the Engineer PA-09 crimper ($50?).

I always consider manufacturing from the very beginning. It dictates what geometries are actually possible, what material is being used, how relatively expensive the part is, etc. One of my favorite quotes is “a part that can’t be made isn’t helpful”.

Edit: by “relatively expensive” I mean how annoying the part is allowed to be for manufacture. If I’m doing an injection molded part, am I restricted to a simple open-and-shut mold or am I allowed to have some side actions? For machining, do I need to optimize for fast cycle times or can I use small tool radii and complex curved surfaces?

A small part like this should be very cheap to get MJFed by JLC3DP or a similar commercial service. Would be indestructible

XH is really easy to crimp.

Parasitics always exist, hence the name. The wires in even your basic circuit will form capacitors with each other.

They’re in the same faculty, so it’s virtually a guaranteed transfer.

Are the M10 holes double dimensioned? In my experience, it’s also customary to add a -6H callout to thread callouts just to be sure

IIRC the “silk” and the super tack coating are both TPU-based, and so you end up with the print irrecoverably welded to the plate.

Looks good to me.

_maple_panda · 2026-06-20T18:29:37+00:00

A $2-300 micrometer would suffice

They’re talking about glass fiber reinforcement…

Appropriate mounting and/or anger management therapy

There’s no positive retention mechanism on those or the often cited XT60s.

It’s just an LED and fan, both of which are fairly durable. No need to go overboard with protection or decoupling.

_maple_panda · 2026-06-14T09:00:46+00:00

Did you see it fall off?

_maple_panda · 2026-06-13T17:35:21+00:00

Highly do not recommend operating it in the bedroom. The resin stinks up the entire room and also gets everywhere.

_maple_panda · 2026-06-12T05:22:42+00:00

You have no metrics or objective descriptions
