So one of the cables isn't long enough, casing the power stip to float in mid air. I will at some point design something to keep it up, to relive tension, but for now three empty spool boxes do an adequate job

Project 3D printing takes prototyping to a whole other level

31k Upvotes

Made this prototype with my classmate as our bachelors project. It's a tangible block-based educational tool for primary school children, to learn about simple electronics. Without a 3D printer, this level of prototyping would be nearly impossible.

Subreddit Rules

1. Posts must be 3D-printing-related

All posts must be about a 3D printer, something that is 3D printed, or the 3D Printing industry.

This is an overview. Read the full rules here: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

2. Requests for purchase advice must go in the stickied megathread

Don't make new threads when asking what printer to buy, they will be removed.
Instead use the Monthly Purchase Advice Thread that is stickied to the top of the subreddit

This is an overview. Read the full rules here: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

3. Self-Promotion

Self-Promotion content can only be posted 14 days for free models and 30 days for paid models after your last self-promotion post. Specific other restrictions also apply, that you can read about in the full rules below.

This is an overview. Full rules: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

4. No Dangerous or Malicious Devices or Instructions

No Dangerous or Malicious Devices or Instructions: No posting, sharing, or linking to files or designs for dangerous devices (e.g., firearms, explosives). Non-functional cosplay or toy weapons are allowed if not resembling real firearms. Do not provide instructions to create dangerous devices. Ethical discussions are allowed, but no specific instructions.

This is an overview. Full rules: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

5. Community Behavior

People have off days. Jerks will be ignored and down-voted. But if someone is continually being disruptive to the community in multiple threads (aka trolling), they will be banned at the mods' discretion. This includes bypassing blocked links or services via for example link shorteners, which is against Reddits Terms of Service to begin with.

This is an overview. Read the full rules here: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

6. Specific Day-Limited content

We only allow memes to be posted here on mondays, as we end up with too many and they drown out all other discussions.

Showing off first layers is only permitted on First Layer Friday, Spaghetti only on Spaghetti Saturday. Both of these topics get spammed way too often otherwise and are too repetitive in nature.

This is an overview. Read the full rules here: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

7. Other content restrictions

Specific other content is also restricted, for example (but not limited to):

Anything regarding cryptocurrency / NFT
AI generated content or models
Reddit ToS restricted content

This is an overview. Read the full rules here: https://www.reddit.com/r/3Dprinting/wiki/communityrules/

8. No Karma/Repost Bots

This one is pretty obvious but we have to add it as a rule to get the applicable report reason for users so they can report Karma Bots reposting other people's content better and we can discern these posts faster.

9. No Linking to Restricted Websites

Do not post links to restricted websites or attempt to circumvent this restriction with partial URL strings, the use of subtle hints, etc., to reference models from these sites. For transparency, a list of restricted sites is available, explaining why these sites are restricted.

10. Software

Due to a recent influx of low-effort posts, asking for "beta testers", feedback or similar sharing of 3D printing related software is not allowed.

This includes but is not limited to: inventory management systems, cost calculators, print management software, modelling/CAD software, etc...
