Ultimaker 2+ Printhead spacer

Recommended Posts

Hi All,

We do our best to make sure your Ultimaker leaves our warehouse fully calibrated and they remain so until you unbox it and start your first print. We trust DHL and FedEx care for your package the same way... -.-' ... but we have learned that regardless of our careful calibration and special packaging your precious Ultimakers do not always arrive in mint condition..

Alternatively, when you have disassembled or cleaned your printhead you need to put it back together again too. Ideally, as close as possible to how it left our warehouse. One of the parts we carefully calibrate on the Ultimaker 2+ is obviously the printhead. It is a rather delicate part of your Ultimaker.

To help you get your Ultimaker 2+ in its best shape, we wanted to share this spacer with you.

3D Print this spacer, and place it in your printhead to determine the ideal space that influences the tension on your TFM coupler and hot end. Once placed, tighten the 4 thumbscrews accordingly until this spacer is clamped in the head.


- The small part in this spacer, the part that fits in your printhead, needs to be 16,8mm.

Make sure to measure this part before you apply it in your calibration run.

- Tighter is not better. It is 16,8mm for a reason. When tightening the 4 thumbscrews do not overtighten them.

With most materials, but especially PLA, it can deform under the pressure if you tighten it too much. This will undermine the function of this spacer. Therefore, make sure it is tight, but stop tightening when the spacer is clamped in your printhead.

This is a tool to help you calibrate your Ultimaker 2+. Use it wisely.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
