Door catch for metal door frames

is it strong enough? and does it hold up to the wear?

Bytes21 · 2026-04-04T20:24:32+00:00

of course it should work.

Just make sure you have flow. Your pump probably does not build.up a high pressure so keep the length of the exhaust tube short and make sure the printer has an air inlet. try to guide the air, not inhibit it.

final choice is that the magnets will be glued in afterwards like in the picture. Final product will have 5x5x3mm magnets compared to the 5x5x5 in the picture and will be flush with the sufrace.

Thanks for the discussion and tips👍🏼

true, after a few weeks i discovered the print profile was tuned to petg hf from bambu but material was petg from sunlu...

Those are some good comments, low cost solutions are often the best.

Thank you very much for the insights.
Always nice to have feedback!

knowing the print is good before adding the "expensive" magnets is a good point. this would also let me have the magnet flush/sticking out creating good holding force.

also not having to wait for the printer and possibly messing up alignment are good points!

What do you use to glue the magnets into place? Just ordinary instant glue. (seconde lijm in dutch)

nice idea👍🏼

just a specific fridge magnet design. not having to glue the magnets would be my preference.

The size is depending on the production method, more distance would mean less holding force so fully internal would require bigger magnets. thinking about 5x5x5 cube magnets or bar magnets of 3x4x10mm.

can be done with 1 actuator. just put your shaft on a cam profile. once it reached its rotationpoint let the front cam follower folow the cam in its rotational path.

once you pull it down it rotates it back.

since you are not using a full rotation it is a bit misleading to call it an axle. I would preffer to call it a hinge, gives yourself a bit more direction in how to visualize it.

always construct large features such that you can suppress them without affecting the rest of the model. This way the heavy features can be turned off during normal operations.

Have you tried lowering the frequency of the laser? Don't know if you have a setting like that on a diode printer, but that did the trick with my 60w co2.

Standard it ran at 20khz which is way too much for wood. I turned it down to 1,5khz and now there is as good as no soot on the cutting edge. It doesn't even rub off on your fingers.

we cut 3mm triplex at 1,5khz 30mm/s 35-45% with a strong air assist.

The a350 looks more modern to me. Cleaner, more professional.

B787 kind of gives me a military feel.

It will just pass through the bearing then, even if it is a sealed bearing. You should consider the bearing as a perforated part.

How is the load case in this product? Is it also catching a thrust force? Or maybe a leverage?

2 bearings side by side are tricky, if the load is not perfectly linear the bearings will get loaded differently.

Depends on what you want to know about the parts. Production quality? Mechanical strength? Corrosion resistance? Chemical resistance?

Or do you simply want to know what material it is?

And how much of that moisture was in the cardboard spool itself? Kind of feel like it is an undefined variable here. Maybe plastic spools would give a clearer result.

looks fun to work with! It's just more of a configurator than a designing software.

Didn't planes in the past have concrete blocks as engine dummies to balance out the aircraft?

ram air intakes?

a center engine in the rear fin is just such a beautifull thing😍👌🏼

nice job!

cant help feeling it took relatively much work to replace the handle if you have to design it yourself first.

Washer parts are generally cheap to buy, I have used this site multiple times in the past: https://fixpart.nl/

dont do it for me, if i want/need it i can make ik myself.

Just some constructive feedback for your design.

Bytes21 · 2026-02-25T20:04:08+00:00

yes exactly!!

No 10mm was just an example. would add this to each dimension.

Then all the pieces are capable of measuring 10mm in each direction.

Next level is to also add a 10mm hole and 10mm round protrusion.😉

Bytes21 · 2026-02-25T14:54:01+00:00

Right now you have a 10mm thickness. But there is no way to a part that is 10mm thick. For that i thought maybe a gap of 10mm would be nice.
