Updated May 2018 - better block (v2)
A simple holder for PCB work.
Print 2 of each STL file. (use V2 block)
Push an M6 bolt through the top hole of a frame, slip on a spring (washers optional) and glue into a block.
2 pieces of M8 threaded bar through the bottom 2 holes. slide together to hold PCB, end frames will grip the threaded rod.
Wrap an elastic band around the each end of each thread if required or add some M8 nuts to cinch it up.
- M6 bolt x2
- spring x2
- washers x4 (optional)
- M8 threaded bar - cut to any length you want (or 8mm wooden dowel)
- Hot-melt glue or similar
- Rubber bands - to hold frames (optional)
- M8 nuts - to hold frames (optional)
The glue only needs to be strong enough to prevent the spring pushing the block off the end of the bolt.
The spring should be able to grip the PCB without damaging it. (TIP: I cut the springs out of pump-action soap dispensers - just the job :) - or buy a tray of assorted springs off eBay for a few quid.
