Begin with the real constraint
Decide on the addition before choosing the fill level, because pieces change volume and distribution. The aim is a small setup you can actually complete, not a larger collection of equipment. Lay out what you already have and notice the step that creates friction before changing anything.
Check the fit before going further
Check manufacturer guidance for when a machine accepts additions; avoid forcing large pieces into a mechanism. Conditions and specifications vary, so treat this as a question to verify with the relevant maker, venue or source when it applies. A quick trial with the actual objects is more useful than a promise based on a photograph.
Finish where the next session begins
Keep the finished container ready and do not turn one batch into a counter full of leftovers. Take a moment to check that the result is accessible, safe for your situation and simple to repeat. If it still feels cumbersome, reduce the scope before adding a new purchase.
