Puro's Base for Gridfinity

Alternate 1x1 base part for Gridfinity boxes. Prints faster and with less material. Designed for 0.8mm and 0.6mm nozzle diameter with Arachne slicer engine.

Single centered magnet (10mm x 3mm) with glue connection. Idea is to use metal sheet below grid for fast, easy and cheap "magnetic" base. Uses less magnets than standard solution.

How to use this? Completely new boxes

Reference the last photo.

1. Create grid of Puro's Bases (42mm x 42mm grid). [Orange]
2. Add solid 2mm slab over the bases (total height is now 7mm). [Gray]
3. Round the cornes or the slab, 4mm radius.
4. Pull 1.2mm wide wall along the sides of the slab. Choose height in steps of 7mm. [Blue]
5. Pull Puro's_Stacker_Profile along the top side of the wall. [Red]

Based on my testing this is around 30% faster to print and uses 0.5 meters less material than standard base.

My very non-scientific test results

General settings for comparison

• Using Ultimaker Cura 5.1.0
• Times shown are Cura's estimates
• 0.8mm nozzle
• 0.8mm line width
• 0.4mm layer height
• 1 wall line
• 2 top layers
• 20% infill, Grid
• No support
• No build plate adhesion
• First layer is significantly slower than other layers. ~20% speed.
