Brompton Seatpost Sleeve Alignment Tool

35.5mm outer and 32.5mm inner diameter for perfect alignment of Brompton seatpost sleeve reamer. No need for additional sleeve or fancy reamer, just get a cheap 32mm reamer and be back riding for a quarter of the cost of one from Brompton. I printed it from ASA since that’s what I had but anything would work so long as it has good layer adhesion. Set seam to random to prevent a bump forming.
