Here we have the ultimate in 3D printer test models, designed by user CtrlV on Thingiverse free to download. The idea was to create a universal test, differences in the printed models can be compared between different makes of 3D printer and different machines of the same model, that way users can tell if there is a problem with their machine and also use peoples experiences to select a make of 3D printer that works well.

The 3D model file was developed by CtrlV, who works for a 3D printer developer so that they could test their own machines

The model takes ~50mins to print and uses <=4m of 1.75mm filament on a FFF 3D printer. The printer should be set to its best resolution with an infill of ~33%. To check you printers performance check the following attributes:


  • Test attributes

    • Size: the object is 4 x 50 x 50 mm (baseplate)
    • Hole size: 3 holes (3/4/5mm)
    • Nut size: M4 nut should fit perfectly
    • Fine details: pyramid, cone, all numbers
    • rounded print: wave, half sphere
    • minimum distance between walls: 0.1/0.2/0.3/0.4/0.5mm
    • overhang: 25/30/35/40/45
    • flatness: all flat areas

Give it a try and see what you get. Remember to let us know, make a comment, and send us your photos of your finished models

Returns & Refunds

Firstly, if you want to return a product or you have a faulty product please get in touch as soon as possible!

To prevent ordering incorrect items, if you are unsure just ask and we can offer some guidance. However, bear in mind that we cannot say whether a particular product will be right for the purpose that you intend to use it for.

You can return your goods to iDig3Dprinting for any reason within 14 business days following receipt at your delivery address as long as they are in a re-saleable condition.

Filaments & resins cannot be returned once opened as once exposed to air these items perish.

Downloadable goods and 3D print samples cannot be returned and no refund will be issued.

Shipping costs of returned items are paid by the customer

A full refund will be issued for unopened items that are returned in their original packaging that are in a “as new” re-saleable condition minus additional costs that are incurred by iDig3Dprinting like payment processing fees, custom duties or charges.

We are afraid we cannot issue refunds for products that have been defaced, altered, used, or damaged in any way. All requests for refunds are subject to inspection by iDig3DPrinting of the returned item. We are not a charity or a lending library.

Refunds and returns for faulty items works a bit differently. Faulty goods can be accepted for return upto 60 days from receipt of the goods (However we prefer to offer diagnostics and repair solutions prior to an actual return, its better for the environment). After this time you will need to contact the Manufacturer. A repair or replacement will be issued for faulty goods once they have passed inspection and been found by iDig3Dprinting to be faulty.

This is a brief account of our returns policy. For the full terms please see our Terms and conditions page. Content on the Terms and Conditions page supersedes this content.

How to raise a return request

  • email idig3dprinting at support@idig3dprinting.co.uk and we will issue a Return Authorization Number (RAN).
  • send the goods back in their original packaging.
  • Once we receive the goods back we will then check them and if everything is as it should be be will issue a refund.
  • If appropriate Refunded payments will then be issued using the original payment option. The time it takes to land in your bank account is determined by the payment gateway used not us.

The main thing is please communicate with us. We are not omnipotent!

We can be quite flexible but this is built upon a foundation of mutual respect between our customers and iDig3Dprinting.
