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.

Good to know before you order

TPU has a £11.50 print-order minimum. ABS, ASA, PC, Nylon and PETG-CF have a £46 minimum; PA-CF has a £69 minimum. Delivery is shown separately in your cart.

Need a few parts? Add them to one cart. One order minimum and one postage charge cover the cart: £6.90 for standard materials, £11.50 with TPU, £46 with ABS, ASA, PC, Nylon or PETG-CF, or £69 with PA-CF.

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 collection of calibration test pieces covering a range of common printer checks, including thin wall tests, dimensional accuracy cubes, overhang tests and bridging assessments. The set gives printer operators a structured way to assess machine performance and tune settings when commissioning a new printer or trialling a different filament. PLA is the usual choice for calibration work, as its consistent behaviour makes it straightforward to identify and correct print quality issues.

Original maker's notes

By coasterman on Thingiverse · CC0

I've taken all the calibration prints out there and condensed them into one place. I have here:

.5mm thin wall
20mm box
20mm hollow box
50mm tower
perimeter width/t tester
precision block
overhang test
oozebane test
bridge test

and more to come.

All designs are my original work and not taken from other users. But they are inspired by other users.

The 20mm box, thin wall, and 50mm tower are ideas from Spacexula's great calibration set http://www.thingiverse.com/thing:2064, and the other ones are my ideas and not influenced by others. After Spacexula's calibration set, there is quite a derivative tree.

Here are some combos I have found with my MK5 extruder:
(In order of: Layer Height, Width/Thickness, Feedrate, Flowrate PWM)
.36, 1.528, 34.1, 255
.3, 1.789, 42, 255
.2, 2.521, 35, 197 *This is still experimental, most prints I try with it fail :(

Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.

Printing The Essential Calibration Set

For The Essential Calibration Set we would normally reach for PLA — it is the easy, economical default and suits the majority of models. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
