cardboard fold roller #3DThursday #3DPrinting

Up your cardboard crafting creases with this print from cocomynamieiscoco on Thingiverse:

Designed this fold roller (I know it looks like a pizza cutter ^^) to make clean folds on cardboards.
I use a section of brass cylinder (external diameter : 5mm, internal diameter : ~4mm) to act as a bearing and prevent the wheel to wear out too fast on the screw.
Designed for M4 nuts and screws (it requires 3 of each), I used a nilock nut on the wheel one to be able to lock it without tightening it too much. It allows the wheel to roll freely.

When using it in the same direction as the cardboard ‘grooves’ don’t press it too hard or it could cut into the cardboard. After a few test I realised you don’t have to press it really hard in any direction to make a proper fold, even on thick cardboard.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
