UPDATE 03.01.2022
I updated the bracket because the walls are a little bit to thin. Now it's also the same design as my wirecutter bracket.
A bracket for a longnose pliers. Fits on a IKEA Skadis plate. Base on the Fusion 360 peg models from Rkimmell73 https://www.thingiverse.com/thing:3734897
You can find the whole IKEA Skadis pegboard one my blog (article is in german): https://krisennerd.de/ikea-skadis-werkzeugwand
