A1 Mini top spool mount adapter

A1 Mini top spool mount adapter

With the A1 Mini top spool mount adapter, you can move the original spool position to the top of the Z-axis. This not only makes the A1 Mini look cooler, but also fulfills one of its most important functions: it saves space behind the printer, allowing you to place the A1 Mini closer to the wall.

The A1 Mini top spool mount adapter includes modules for holding the PTFE tubing. This allows you to choose the position on the top spool mount to suit your needs, or simply download the RAW module and create your own custom module.

What you need

Everything you need is already included with your A1 Mini - you don't actually have to buy any extra materials unless you don't already have them.

• 1x M3 screw - for the module (use one of the securing screws that you

  removed when setting up the A1 Mini)

• 2x M3-8 screws - for / from the spool holder base plate
• The existing PTFE tube connector

I hope you like my model, and I look forward to your pictures and feedback. Below, I've included mounting instructions and links to some models that I use with the A1 Mini.

Assembly

A simple and quick assembly guide for you, with pictures and text - I hope it helps!

#1 Remove the PTFE Tube Connector

To remove the PTFE tube connector, unscrew the cover behind the X-axis motor. This will allow you to press the clips together and remove it.

#2 Top Spool Mount Adapter

First, remove the gray cap on Z. Unscrew and remove the white plate. Next, screw the adapter onto the top using the same screws.

#3 Spool Holder Base Plate

Install the spool holder base plate using two M3-8 screws, reusing them from the original position. Then, slide the spool holder into place from top to bottom.

#4 PTFE Module

Install the PTFE module by simply inserting it into the back panel and securing it with one M3 screw (use one of the securing screws that you removed when setting up the A1 Mini). Now you can also install the PTFE tube connector.

Changelog

11.11.2025 I've slightly adjusted the holes and the print profile of the top spool mount adapter to achieve even better print quality.   I've also modified the PTFE module – Longer – to make it even more stable.   In addition, I've updated the model images and added instructions with text and short videos.

28.05.2025 A bug was fixed in the "Module with A1 mini PTFE holder V3 - Center": The step that locks the tooth of the PTFE holder was missing, which could potentially cause the PTFE holder to not stay in place and fall out.   Thanks to @filin for the tip and support 💪

14.03.2025 I slightly adjusted the holes for attaching the spool holder to make it easier to screw in the screws without compromising stability. I also adjusted the print profile to achieve better print quality.

05.02.2025 I added the module "Module with A1 mini PTFE holder - V3" in a version that the PTFE tube is positioned more in the middle of the spool.   Module name is: Module with A1 mini PTFE holder V3 - Center

30.09.2024 I have added the "Module with A1 mini PTFE holder - V3" in a longer version so that filament spools with larger diameters do not rub against the module   Module name is: Module with A1 mini PTFE holder V3 - Longer
