Upgrades & compatible parts for the Prusa MINI / MINI+
The Prusa MINI / MINI+ (Prusa, 2019) has a 180×180 mm bed, a bowden setup and a bedslinger design. Those specs decide what fits. Here's the matching upgrade and spare-parts list — free printable mods and buyable parts.
PEI spring-steel build plate
Look for a 180×180 mm spring-steel plate — that exact size is what fits.
Nozzles (brass / hardened)
MINI uses an E3D V6-style hotend — standard V6 brass/hardened nozzles fit.
Hotend / high-flow upgrade
All-metal or high-flow (CHT/Volcano) hotends boost speed and let you print high temps — popular on this printer.
Extruder & drive gears
A dual-gear or direct-drive conversion is the single biggest quality upgrade for this bowden machine.
Part-cooling fan duct
Enclosure
An enclosure keeps ABS/ASA warp-free and cuts noise — ready-made tents and printed panels both work.
Spool holder
Tons of printer-specific holders exist — from simple arms to bearing-mounted spinners.
Filament runout sensor
Many newer models already include a runout sensor — check yours before adding one.
Belt tensioner
A printed X/Y belt tensioner removes belt slack and tightens up your dimensions — cheap, high impact.
Cable chain / management
Tidy the wiring and protect it from snags — a satisfying first print upgrade.
Filament (PLA / PETG)
The one thing you'll buy again and again — match diameter (1.75 mm) and dial temps to the brand.
