Top cover for Snapmaker U1 using 60L Box One from Action

We all know the IKEA SAMLA top covers for Snapmaker U1. I didn't want to drive to the nearest IKEA so instead I went to ACTION and picked up a larger 60L storage box (link) and spent way longer designing this adapter than the IKEA trip would have taken. This 60L box is already tall enough to clear the U1's PTFE tubes and cables, requiring no extra height from the printed adapter. Besides, it has WHEELS and wheels make anything go faster!

The raised lip keeps the storage box secure enough to not shift around during printing, while still being easily removable. The adapter ring uses 4 round feet to index with the 4 circular slots on each corner of the U1, as well as the 4 small nubs along the sides and a rib to support the overhang in the rear. 

The adapter ring requires only about 135 grams of (PETG) filament to print. No supports are required (the small bridge in the feet prints just fine) and everything has a large flat side to print on, so no brims or mouse ears. 

The model comes pre-split into several pieces <270mm in length and the entire adapter can comfortably fit on 2 U1 buildplates. All pieces use some kind of indexing feature (e.g. dovetails) to connect, but still require glue or a quick touch with your least favorite soldering tip to connect securely. 

Version history:

• 1.0 Initial release

• 1.1
  - Shifted the storage bin forward to meet the front edge of the printer, slightly reducing the need for room behind the printer. 
  - Removed the part covering the 6-pin 24V expansion port between PTFE tube 2 and 3. 
  - Modified the rear support to slip on from the front and be captive from top and bottom.
