holder for sharp rod, pen or pretty much anything circular that has about 5-15mm diameter. (the photo is from old version) got the idea from this video: https://www.youtube.com/watch?v=sNh0ubRcTYU You can easily change parameters with Fusion 360 and fusion file You will need: 8x 625zz bearings (5x16x5mm) 16x M5 washers 4x M5 bolts (min. 35mm) 4x M5 nuts 6x M4 bolts (lenght in Body2 section) 6x M4 nuts 2x M3 bolts (lenght in Body 3 section) 1x M3 bolt (8-10mm) 1x M3 nut 2x rubber bands Print settings: 0.2mm layer height Body1: -only part that needs supports -pause at layer 93 so you can insert 6x M4 nuts during the printing in cura: extensions->Post processing->Modify G-Code->Add a script->Pause at height->Pause at: Layer No. and Pause Layer: 93 -first layer after the inserted nuts will be probably printed badly, but it fixes itself after that Body2: insert=anything you put in (rod,pen,...) -M4 bolts lenght: ver.1=30+insert diameter ver.2=20+insert diameter Body3: ver.1: insert=10mm M3 bolts=+-15mm ver.2: insert=5mm M3 bolts=+-10mm ver.3: insert=15mm M3 bolts=+-20mm Body4: just print as it is
