Event Horizon

Description from Cubicdissection:

Tim has been doing some very interesting work with regular burr pieces interacting with loose elements inside cages. I wanted to make one of his designs but there were several to choose from and it was a tough choice. I eventually settled on Event Horizon as a good representative of the concept. Four standard burr pieces dance around with a single cube in a box. The box has an unusual opening in the top and bottom, and hidden protrusions inside. The level 20.4.6.7.3 (whew!) solution is very difficult, but the feeling you get when the last piece slides into place is worth the effort. Given the unusual configuration, eye catching splines and precise construction, this one's a looker all the way!

Construction of this puzzle is excellent, with close tolerances and strong joinery. Fit is excellent, precise yet with enough room to accommodate a bit of seasonal wood movement.

Over the next few weeks i will be selling off my entire collection. I have been collecting for almost 10 years, and also have some rare puzzles. Most of my collection is wooden puzzles, but a few metallic have sneaked in too.

I can offer to hold your won item, and combine it with other current or coming auctions, to save you on shipping.
Having sold many puzzles on the Cubicdissection marketplace (https://market.cubicdissection.com/display-feedback/keezor), i have a lot of experience packing and shipping puzzles, and so far have not experienced any damaged shipments.
I take great care to pack the puzzles, so they can withstand the brutal handling the packages often get.

Shipping cost is calculated after the auction is finished. For 1-4 normal sized puzzles, expect around 15-20 EUR with tracking for most countries.
Payment by Paypal(fee 5%), Wise(fee varies, cheaper than paypal), SEPA/EUR(no fee), Bank transfer is accepted. 
Fees will be paid by the buyer.

I can also offer split payment, where you pay 20% of the order now, and the remaining next month. I will ship the puzzles, when they're paid in full.
