“The Prusa Mini and Mini+ are remarkable machines, especially for their price. Make them even better with these Prusa Mini upgrades and mods!”
The Prusa Mini and Mini+ are compact, affordable, and high-performing machines. From the makers of the famed Prusa i3 MK3S, they’re made to be both great first printers and rugged workhorses. Underneath the approachable price tags are powerful electronics, a clean interface, and built-in network connectivity. For around $400, however, you’re not going to get all of the bells and whistles. Compared to the bigger i3 MK3S, the Prusa Mini and Mini+ are missing the Bondtech drive gears and a built-in spool holder, among other features. Thankfully, those looking to upgrade their Minis have the chance to do so with a host of printable and purchasable upgrades. These bridge the gap between the entry-level Mini and the performance, polish, or convenience that you might be looking for. Because of the similarities between the Mini and Mini+, all the mods included in the list should work for both printers.

So, without further ado, let’s dive into our list!
First up we have the upgrades that come with a price. While there’s a small upfront investment in purchasable mods, the proof is in the improved printing!
One of the premiums you lose with Prusa Mini is the genuine Bondtech IFS Extruder drive gears of the i3 MK3S+. While this is perfectly acceptable for the price range, users looking for slightly better performance (and willing to pay for it) will benefit from the famed Bondtech system.
This upgrade kit swaps directly into the machine, improving precision, durability, and retraction performance. An in-depth tutorial is included in the setup guides to help you through the upgrade, though some prior experience with 3D printers may be helpful.
Note: Due to a firmware change, the necessary modification to the steps per mm settings can’t be stored permanently on the motherboard. Instead, follow the official installation instructions to modify your slicer’s start G-code or refer to this forum discussion.
What it improves: Retractions and extrusion precision
Who made it: Bondtech
