Welcome to Sketchfab 3December 2019! Read this first

It’s time again for 3December! It’s an opportunity for you to challenge yourself with a new 3D topic each day for 3 weeks.

Prompt reminders will be posted each day from December 2nd to December 22nd, and you will have until January 1 to complete your models. Create and share a collection of all 21 models to be entered into a prize raffle at the end of the month. And to see all of the challenge entries, check out the tag gallery.

For those eager to get started, here is the full list of prompts and the days in December they will be posted:


  • Use any tool and workflow you like to create your models.
  • The models can be static or animated.
  • Give your models titles and brief (max 50 words) descriptions.
  • Submit only new work.
  • Once you’ve created your models, upload them to Sketchfab, tag them #3December2019 and whatever that day’s tag is (tags posted daily on the Forum).
  • Create your own thread in the 3December Entries forum to share and keep track of your progress.
  • Use the #3December hashtag if you want to share your entries on social media.

That’s because nobody has uploaded any 3D models and tagged them yet :slight_smile:

Can we post them in different order? For example starting with day 4.

Yep - any order you like :+1:


Thank you!

Does it work to post all 21 entries in one file? seeing as I have one upload available :))

Why don’t upload them as different files free to download :hushed: ? just curious

Seriously, is it day 14? fuck … but what’s wrong with me, god, what a stress! :woozy_face:

When and where do we need to share a link to our collection?

From my previous experience on challenges, I assume there will be a post in this thread at the end of this challenge there Sketchfab team will give you all info what you need to do.


Thanks!!! a lot.:smiley::smiley::smiley:
