We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

About this print

A calibration model used to assess a 3D printer's bridging performance, that is its ability to print horizontal spans without any support material underneath. The design includes a circular section on the bridge and hollow struts to reduce print time. It is commonly used by hobbyists and technicians when dialling in printer settings. PLA is a suitable material as it bridges predictably, making weaknesses in printer configuration straightforward to identify and correct.

Original maker's notes

See if the circle on the bridge comes out ok!

Struts are hollow to speed printing.

My test with this show me that I must print bridges slowly!
