3D-printed accessories for Hymer and Dethleffs multifunction rails. Designed, printed, and tested in a real Hymer ML-T.
Hymer multifunction rail accessories will NOT fit Dethleffs rails, and vice versa. Each listing clearly states which system it fits. Not sure which rail you have? Message us before ordering.
















"The products fit perfectly into our Hymer Yellowstone and make travelling even more comfortable. Phil's service is exceptional."
"Really pleased to finally have a good range of accessories for my motorhome rails. Phil printed versions to fit my Dethleffs rails perfectly."
"Excellent quality. Fits perfectly onto the Hymer shelving system. Beautifully packaged and arrived quickly."
Every Hook-In Elements product starts with a real problem noticed on the road. I own a Hymer ML-T and use the multifunction rail system every trip. If something frustrated me, I designed a fix.
Products are 3D printed in PETG, tested on my own rail system, and refined before they go on sale. No generic designs, no guesswork.
