Magnetized part tray to keep your parts from getting scattered all over the place.

Designed for 18x5mm magnets as it's what I had on hand but let me know if you'd like to have other magnets supported and I'll do it when I have the time.
Printed in PETG-HF
If you print it let me know how you like it.

How to insert magnets: When the print pauses, insert the magnets and the print plate should help them pop in. If not just give it a gentle nudge. 
 Ensure the magnets are not sticking out of their slot, if they stick out the nozzle may hit them.
