I had the heated bed mounted to my printer MacGyver style, using clamps to mount the bed to the frame and bulldog clips to hold the glass to the bed. See the photo's. It made the printer look cheap, and I could not wire up the heated bed because its connections were clamped to the printer frame. These adapters solve all the problems above. With these adapters, you can wire up the heated bed, and the printer instantaneously looks 500€ more expensive. Especially when you also print the Kossel XL 2020 corner dust covers :-)


The parts you need

  • 3x heated bed adapter (one with space for the wires)
  • 3x heated bed adapter cap
  • Kossel XL
  • Round heated bed with ears for Delta Rostock / Reprap Ø 265 mm
  • Glass plate Ø 260 mm
  • 6x M3, 8 mm screws
  • 6x M3 nut
  • 12x M4, 12 mm countersunk screws
  • 6x M4 nut
  • 6x M4 (hammer) T-nut

Build instructions

Solder a thermistor to the heated bed and fixate it with kapton tape. Wire up the heated bed and thermistor to the electronics of your printer.

Place the M3 and M4 nuts in the adapters. Mount the heated bed to the adapters using the M3 bolts. Mount the heated bed with the adapters to the printer frame using the M4 bolts and (hammer) T-nuts. Mount the glass plate using the adapter caps and M4 nuts.

Note: the pile of parts in the last photo were created during the prototyping process.

If you only use the heated bed for PLA (recommend bed temperature 20-35C) you could use PLA, otherwise I recommend using PETG or ABS for the adapters.


Calibrate you printer before usage! Remember that your bed is lifted around 5 mm.

Помогите пожалуйста! Все напечатал как у Вас, стол лег идеально, а вот верх мал оказался. Хотя отверстия все совпадают. Стекло 260 на 3 мм. Если распечатать основание и положить с верху, оно держит но не красиво ;-(

How much mm needs to be cut off?
I have uploaded two extra, one for 262 and one for 263 diameter.
Does one of those fit? Let me know, I can edit and upload more.

Спасибо! Буду пробовать. У меня стекло проходит в ровен со столом (кроватью) только без ушей ;-).
А какой размер стекла у Вас? На фото оно меньше стола.

The diameter of my glass plate is 260 mm. Yours must be 265 mm like the heated bed. I have uploaded the file 265_mm_heated_bed_adapter_cap.stl for you. The file for the 260 mm bed is renamed to 260_mm_heated_bed_adapter_cap.stl. Let me know if this works for you, and please share some photos of your print (I Made One) when it fits! Where did you buy you glass plate?

Как проверю, фото сделаю. Это зеркало, вырезанное у знакомого стекольщика. Я на него перешел еще когда у меня был 3D принтер Picasso. Сейчас собрал свой, самодельный на подобии Kossel XL. Плата управления Lerdge 3D.

Custom made glass bed, nice! The Lerdge Controller Motherboard looks good and interesting. Especially in combination with the color touch screen. I was not ware of its existence. Are you satisfied with it?

Полностью! Удобный, тихий и много дополнительного оборудования, которые работают сразу после подключения!

Klinkt goed! :-)

Ziet er heel goed uit! Bedankt voor de plaatsen van de foto's. Fijn dat ik je heb kunnen helpen. Leuk om te zien dat mijn ontwerpen ook door anderen worden gewaardeerd en geprint!

Hello, this is a very nice design, I was wondering if you used any kind of insulation under the heated bed for protecting the electronics ?

No insulation but four fans around the main board to keep it cool. Next time I would not place the board underneath the heated bed.

do you know how long the size extrusions are? 360mm?

The side bars are 360 mm indeed.

What heat bed did you use?

I have uploaded two extra images of the heated bed. Search ebay / aliexpress for 'Round heated bed with ears for Delta Rostock'
