Raspberry Pi Pico development (screw terminal) case

A development case for the RPi Pico for quick testing with loose wires.

Files:

• PicoCase-*: Single material individual STLs.
• PicoCase_MM: Multi-part STL for multi color print.
  • For PrusaSlicer: After the STL is opened→right click→split→To parts. 
  • Do not print the top and bottom together at the same print.

Features:

• Screw terminals for easy attachments and swapping.
• Compatible with 4mm screwdriver bits.
• Top cover LED indication.
• Decal included for easy pin identification.

Notes: 

• Supports required:
  • For the top cover I used paint on supports for the bridge and avoided the endpoints as to ease the removal.
  • For the bottom cover just use build plate supports.
• I printed in ABS and followed this guide to print two materials with Prusa Mini, but also a single material version is included.
  • Additionally, I used Ironing on top surfaces for better contact between the covers, and fuzzy skin with both thickness and point distance at 0.05.
• Note: on the prototyping board there is one row of holes left free between the screw terminals and the Pico headers.

Additional Hardware:

• M3x4x5 threaded inserts.
• M3x8 hex socket head bolts.
• KF128 screw terminal blocks 2.54mm (use blocks of 10 pins if you want to maintain access to all pins).
• 4mm LED pipe (Cut to length of 7.5mm).
• Through-hole prototyping board: 52x40mm (see picture for assembly). I cut and sanded (symmetrically) mine to size.
• 2x20pin Pin Header 2.54mm (for the Pico)
• 2x20pin Female Pin Header (for the board)
