My very first very simple model made in freeCAD and first printed on a Creality Ender 3 V3 SE. Since I also have a Bambu Lab A1 Mini I thought it's a good idea to publish it not only on Thingiverse but also on Makerworld. This bumper was for protecting a glass door in my kitchen as you can see in one of the photos.

I printed it with Eryone Standard TPU, 15% cubic infill and 0.2 layer height which can result in a fairly stiff bumper. You can use nearly every setting that comes to mind depending on the stiffness you want to achieve. 

Have fun with it!
