This is a bracket for a square perforated board (bott perfo branded, sold by bigdug.co.uk) to hold screwdrivers.
I have designed variations for:
See my other Bott Perfo pegboard models:
All models fit the pegboard without ‘wasting’ pegs - by this I mean that multiple can be printed and fitted to contiguous pegs. Or in other words, the horizontal space that the model occupies does not interfere with the next model if the next available peg is used (see photo with 2 supports).
I print the brackets in PLA, with a relatively high infill and supports. I'm sure PETG would work as well if not better.
The perforated board has square holes with a 9mm side, spaced 40mm apart (centre-line to centre-line of each hole) horizontally and vertically.
The author marked this model as their own original creation.
