Adapter for proprietary big drill bit sets holder inlays (Bosch/ENT sets - diameter 1mm to 13mm in 0,5mm steps - so a lot of drills ;-) ) to use to build a french cleat element on 18mm plate. The drill bit holder inlay is perfect for itself and works fine attached to the french cleat element.
No need to waste filament and print an entire new drill bit holter.
Use this little supporters and you'll be fine.
