A Lock-Pin for IKEA Skadis Pegboard
... so all the Hooks and Hangy-Things that come as an accessory for your IKEA Skadis Pegboard, are not falling off that easily.
Notches can be easily removed. The bevel also helps a bit with printability.
This is a small thing, so make sure your printer is well-tuned so it sticks. The profile I've included should handle it well.
Add a brim otherwise.
