Peg board system

Finally got around to making a peg board for my small workshop. Nothing special and quite simple but works well enough for me.

The FreeCAD source file is provided as “pegs.FCStd”. Feel free to play around with it and change parameters in the spreadsheet. Familiarity with FreeCAD required.

Everything was printed from PETG for strength and flexibility. The multiple colours are because I first ran out of black, then out of green, and was then stuck with purple.

The “peg board.stl” file provided is NOT for 3D-printing but for cutting from MDF on a CNC machine. It is 510x510x18 mm and the largest that I can cut on my 750x750 Workbee Z1+. If you want a different size, it should be easy enough to design your own: the holes are 8 mm diameter and 10 mm depth, with the centres 50 mm apart. The 50 mm spacing only matters if you're planning to use any of the rails (which expect 50 mm spacing).

Various pegs are provided. The part that goes into the peg board has a flat thread so it requires some force to twist in but that should also make it not fall out. The thread-only part is provided as “threaded insert.stl” and can be used to design your own pegs/attachments.

• “peg 25 mm.stl” is just a straight solid peg.
• “peg thin.stl” is a straight solid peg but quite thin (5 mm diameter).
• “peg 25 mm capped” is a straight solid peg terminated by a circular cap to stop things sliding off.
• “threaded peg.stl” terminates in a thread which fits a locking cap. To be used to attach the rails and screw clamps to the board.
• “lock cap.stl” screws onto the end of a threaded peg and meant to be used to attach rails and screw clamps to the board.
• “threaded insert.stl” is just the threaded part that goes into the board. Use this to design your own pegs/attachments.

The threaded peg/locking cap can be used to directly attach holding clamps to the board. Three clamps (small, medium, large) are provided:

• “screw clamp sml.stl”: small clamp.
• “screw clamp med.stl”: medium clamp.
• “screw clamp lrg.stl”: large clamp.

If you want to attach more than one clamp/peg per hole in the board, you can use the attachment rails. Four rails (spanning 2, 3, 4, and 5 holes) are provided. They are attached to the peg board using the threaded pegs/locking caps and have a hook along their outer edge on which various clamps etc can be hung.

• “rail 2-hole.stl”: rail spanning 2 holes.
• “rail 3-hole.stl”: rail spanning 3 holes.
• “rail 4-hole.stl”: rail spanning 4 holes.
• “rail 5-hole.stl”: rail spanning 5 holes.

Hook clamps are provided which hook onto the rails instead of attaching directly to the board. If you want to design your own, the hook profile is also provided.

• “hook clamp sml.stl”: small hook clamp.
• “hook clamp med.stl”: medium hook clamp.
• “hook clamp lrg.stl”: large hook clamp.
• “hook profile 1 mm.stl”: use this to design your own clamps/attachments to fit on the rails.

Peg rails with thin pegs at a 1 cm spacing between pegs are provided which hook into the 2, 3, 4, and 5-hole rails above.

• “hook rail with 7 pegs.stl”: fits the 2-hole rail.
• “hook rail with 10 pegs.stl”: fits the 3-hole rail.
• “hook rail with 14 pegs.stl”: fits the 4-hole rail.
• “hook rail with 17 pegs.stl”: fits the 5-hole rail.
