SolidSlime: solid fidget toy that flows like slime

Love the sensory feedback of slime but hate the mess?
Meet SolidSlime, a 3D-printed paradox. It’s a rigid geometric sculpture that mimics the fluid, disordered manipulation of soft stress-putty or slime.

What is it? A matrix of precision-fit square columns designed for dynamic vertical movement. Twist it, turn it, and shuffle the blocks endlessly in your hand. It looks like a solid block, but it flows through your hands like silk.

Neurodiversity Friendly: SolidSlime is designed with ADHD and Autistic individuals in mind. The rhythmic friction and the tactile "gritty" sensation provide excellent sensory input (stimming) to help with focus and anxiety relief.

Why you'll love it:

• 🧠 Sensory Paradox
  The weight of solid plastic meeting the flow of a soft material.
   
• 🔊 Soothing Friction
  The blocks create a unique, low-volume grinding sound. Use it on a desk for a deeper, resonant acoustic feedback.
   
• 🛠️ Easy Post-Print
  Just "break it in" by sliding the pieces for a minute after printing to achieve a buttery-smooth glide.

Release history

20 May 2026 | New 3x3 bases!   Many of you wanted a dedicated desktop stand for the smaller 3x3 - Stealth Pocket version. I have just updated the "Display Bases for SolidSlime" print profile to include the brand new 3x3 bases (both Pyramid and Diagonal Tower styles!). Now even your pocket companion can have its own elegant throne on your desk.

9 Apr 2026 | New base for 10x10 version   Some of you asked for a base also for the 10x10 version of the fidget toy. Here it is, with a brand new “wave” style.

22 Mar 2026 | New High-tolerance profile for PLA Silk   Some users reported stiffness when using PLA Silk or paints. I just uploaded a new High-Precision Profile specifically tuned to fix this. It uses 0.12mm layers and XY Compensation to guarantee better quality and smooth movement even with expanding materials. All sizes are placed in the same profile on separate plates.

4 Feb 2026 | New 10x10 version   You asked for it, and it’s finally here.  The SolidSlime experience has been pushed to the limit. By popular demand, I’ve added the 10x10 - Mega Matrix profile. This is the ultimate SolidSlime experience: a heavy-weight, two-handed mechanical "liquid" that takes satisfaction to a whole new level.

2 Feb 2026 | New Desktop Display Bases   I have just released a new print profile featuring two dedicated display stands for your SolidSlime. These bases are designed to keep your desk organized and turn your fidget toy into a stunning geometric sculpture:   Pyramid Base: A compact, symmetrical stepped design. Diagonal Tower: A tall, sloped stand that emphasizes the "slime flow" effect. Both stands are optimized for maximum filament savings: since they are non-structural items, the profile uses a single wall and low infill to minimize waste and print time without sacrificing aesthetics.
