Engineering

Hi, I'm trying to get into 3d printing so I can bring my ideas to life. I recently had a baby boy who has started learning to walk.

Problem: His walker moves forward (or backwards) when pushed (pulled) in an uncontrolled manner. When my son attempts to pull himself up or stabilise himself, the walker shoots forward, resulting in him falling over.

I would like to design and 3d print a mechanism which attaches to the wheels of the walker (simple wooden walk bought from Amazon) which controls its forward and backward movement.

Ideally, I would like the walker to move forward, inch by inch, and only when forward force is applied.

I'm a complete newbie and don't have any engineering knowledge. However, to illustrate some of the mechanisms I thought I might need I have attached a few pictures.

Can anyone please help me?

Hey guys!

Is there any one that can do a cut out for me in a Thing? I already asked the creator past few days of the Thing but got no reply yet.

It's this Thing: https://www.thingiverse.com/thing:2600020

On the top (playstation_pi_mini_v3_top.stl) is on the left side a fake LED spot. Here I need a proper cutout so place a real LED here. I've tried a bit to do it with Blender but I'm a bloody beginner. Never had any done with Blender.

I normally mainly use OpenScad for my designs, but some building parts are difficult or slow to create.
Here an exemple of slate roof done with Python programming:

Once the pattern is created, you just change the number of columns and rows, or the slate dimensions.

Hello dear community,

I need help for my master thesis. I am examining explorative behavior on Thingiverse and how it is influenced by personality traits. Therefore I generated an online questionnaire.

I would be very happy if you could take 5-10 minutes to complete my survey:

Many thanks in advance!

Hey guys!

I'm re-engineering a PC Case Fan Grill for my Fractal Define 5 White (https://www.fractal-design.com/wp-content/uploads/2019/06/Define-R5-white_21-2.jpg) because I use now Noiseblocker NB-eLoop B14-3 and they are a bit higher/thicker than regular ones.

Good, now I designed an prototype with Tinkercad and chopped it in 2 parts to can print both in one go. BUT Cura won't these 2 parts shown here on the picture (violet circles). I already tried some variations with and without support, used a alternative Cura version and so on. But in this position Cura ignores these to parts.

Does anyone have an idea?
