Turns out the magnets required are an odd size, combine that with the fact they need to me high temp and you’re looking at he cost of this item again!!I haven’t bothered and instead bought the proper bit direct from Prusa which has worked out miles cheaper! Would love a refund really as this is basically useless now… ## Frequently Bought Together - 12V Y Carriage Magnetic PCB Heated Bed MK52 Heatbed Hotbed Without Magnets for Prusa i3 MK3 3D Printer, with Cables, thermistor - Gimax N35UH Magnets 2062mm for MK52 Heated Bed of Prusa i3 MK2.5/MK3 - BCZAMD Prusa MK4 I3 MK3 MK52 Gold Double Sided Textured PEI Spring Steel Sheet Powder Coated PEI Build Plate for Prusa i3/Ａquila pro/CR6 SE MK2.5S MK3 MK3S, 253.8 x 241MM --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/252892498-12v-y-carriage-magnetic-pcb-heated-bed-mk52-heatbed-hotbed](https://www.desertcart.jp/products/252892498-12v-y-carriage-magnetic-pcb-heated-bed-mk52-heatbed-hotbed) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-12*
