Snapmaker U1 Top Cover with Vent Opening for IKEA Samla and Walmart Sterilite v3

This is an adapter for the Snapmaker U1 to use an IKEA Samla 45L box or a Walmart Sterlite 55L/58qt box as a top cover. It is meant to be a simple but very functional design. You can slide your box back for ventilation. No need to remove the cover or open the door when printing PLA. It is compatible with BIQU Panda Breath if you want an active chamber heater. Cable channels for an optional front USB port and LED bar are integrated. Additionally it has an option for side mounting accessories like extra spool holders or tool holders on each side. I designed it for easy and fast printing and assembly.
You can find links to the accessories and addons for this top cover down at the end of this text.

UPDATE v3 20260313: I added some more cable channels to the design. There now is an opening in the back for the power cable of a Panda Breath. You can also use the cable channels to add a front USB or an LED Bar to the adapter.
There is a print file with only the updated parts if you already have a version 1 or 2. The update is the same for IKEA and Walmart.

Parts:
I made one 3mf file with all parts for the IKEA box and one with all parts for the Walmart box. These are the parts included:
1x all 8 parts of the frame
2x hooks
2x accessory covers
2x plugs for the cable channels in the back
1x plug for the Panda Breath cable channel
6x blocks (IKEA or Walmart)
6x dummy plugs (no-Walmart or no-IKEA)

I also made a 3mf file with only the updated parts if you already have an older version of the adapter and you want to update to v3. It is the same for IKEA and Walmart.
1x the 6 updated frame parts
2x plugs for the cable channels in the back
1x plug for the Panda Breath cable channel

There is also one 3mf file if you want to add a label to the frame. It uses/covers the hole in the front right. (If you are planning to add a front USB port use the labels provided with the addon!)
1x "U1" label 10mm x 20mm
1x blank label 10mm x 20mm
1x blank label 10mm x 30mm
1x blank label 10mm x 40mm
1x blank label 10mm x 50mm


Printing:
Use the filament of your choice. PLA could be problematic with 60°C chamber temperature. Other filament types like ASA might shrink and you have to compensate for that. PETG should be OK and easy to print. I had problems with underextrusion when using the SnOrca generic PETG profile. Might only be a problem with the filament I used. Just test your profiles first or you might have problems with the tolerances.
Depending on your filament choice you might need a brim or mouse ears.
Support is not required.
The labels are meant to be multi color prints. I added a "U1" to one of the short labels as an example. Just choose one of the labels and use the text tool with "Operation" -> "Modifier". After writing and positioning your text (name of printer, IP-address, ...) you can change the filament for this modifier.


Assembly:
Please take a look at all the pictures first! The blocks and dummy plugs for the IKEA and Walmart boxes are coded (one or two dents) to fit only in the right spots. There are holes in the dummy plugs, the accessory covers and the cable channel plugs to remove them with the help of wood screws if needed. The frame should be a nice press fit and no glue is required.

Please share your prints and feel free to remix or build some accessories! Thank you!
