I created these as replacement handles for an old IKEA drawers chest (I think Hemnes but not sure), but I think they can be scaled and adjusted for many other drawers / chest / cabinets, especially for kid bedrooms. My daughters asked for starts and hearts, so there you have it!

Adding Inserts

I highly recommend adding inserts for fasteners. However I intentionally left the insert placeholder out of the model, as they are easy to add in the slicer and this keeps the model flexible for whatever inserts you have available. 

This can be done by adding a cylindrical negative volume modifier to the shape in your slicer. In PrusaSlicer 2.4 this is done by right clicking the shape → Add Negative Volume → Cylinder. My inserts external size was 6.5mm diameter x 8mm height (see attached screenshot). 

Then I added the inserts by heating them with a soldering iron.

Recommended Print Settings

I think these are pretty versatile, and there really aren't any special requirements here. I printed this with PLA at 0.15mm layer height, 15% infill - pretty sure you don't need much more.
