Decided to breakdown the pricing of the upgrade options per kit to help with my decision making and figured it would be worth sharing with the class. All prices in USD.

Feel free to fill in any gaps I may have missed or correct any assumptions I have made. I'll update the OP.

1 Toolhead	Dwarf	Nozzle	Total
$249.99	$20	$30	$299.99

2 Toolhead	Dwarf	Nozzle	Total
$309	$40	$50	$399

5 Toolhead	Dwarf	Nozzle	Total
$459	$100	$130	$689

Facts

• The dwarf boards are always $20 per toolhead.
• Replacement dwarf boards are $57.99 currently.
• A new .4 CHT nozzle in the spare parts section is $26.99. The upgrade for the 1TH is $3 more expensive. For the 2TH the nozzles are $4 cheaper total and the 5TH is $5 cheaper total.
• When just looking at the first column (without dwarf boards or nozzles) The 2TH per head cost is $59.01 (309-249.99) and the 5TH is $52.25 ((459-249.99)/5).
• Price includes import. Not sure how to estimate that cost.

Upgrades and estimated costs

I've left the unknown costs blank below and only put prices for comparable items currently on Prusa spare parts section or other printing stores.

Item	Cost	Notes
Calibration Sensor
GT1.5 Belt x2	$23.98	Prusas current belt replacement price x2
GT1.5 Pulley x2?	$10 ($5 each)	Price from Filastruder (just as a reference). Unsure of current number of toothed pulleys on the XL.
Nozzle Wiper
Toolhead Cooling	$3.99 per head	Assuming just the printed part-Core One replacement price
Bed Cooling Fan	$7.99	Core One replacement price
Bed Cooling Cover
Electronics Cooling Fan	$7.99	Assuming same fan as bed
Electronics Cooling Cover
Misc Printed Parts
Total	$53.95

Assumptions

• Using the above per head upgrade price, I'm estimating the non-toolhead parts are billed around $189.99 (249.99-60).
